Office 2013 for Windows RT
Office 2013 is the headlining application for Windows RT. And it’s a pretty big deal - this is the first time we’re seeing the full Office experience reach a modern tablet platform, at least in the first party sense. In the smartphone world, this wasn’t as much of a distinguishing factor as Microsoft hoped it would be when they included a mobile version of the full Office suite in Windows Phone 7, but that’s because there’s relatively little scope for document creation or editing on handhelds. In the tablet world though, it’s huge. For a tablet to truly be a viable replacement for a notebook, office productivity needed to be addressed.
So Microsoft decided to do something about it: Office 2013 Home and Student Edition ships as a pre-installed part of every single Windows RT tablet. And just like that, almost every non-engineering student I know could get away with a Windows RT tablet as their primary computing device, provided they aren’t gamers or aren’t attached to the idea of local storage. It’s something I couldn’t say about the iPad or any of the Android tablets out there. But I’m getting ahead of myself here. Let’s look at the applications themselves.
Office Home and Student contains Word, Excel, PowerPoint, and OneNote, so you get the core three productivity applications, as well as the one with the most potential for tablets. The one application that will probably be missed most is Outlook, but with Outlook account support for both the Mail and Calendar apps, enough of the functionality is still available. Outlook is more power-user oriented than either Mail or Calendar, but when it comes down to it, Windows RT was created to serve a more consumer-oriented market segment that typically doesn’t rely on the more intricate functionality of Outlook.
Design was always the biggest question about creating a mobile office suite. How much would Microsoft be willing to change the interface to suit a touchscreen input? How much functionality would that give up? How would Excel even work? I don’t actually have an answer, but here’s where the thinking went: why bother designing a touch-centric typing or spreadsheet app if most people are going to turn to a physical keyboard to use it anyways? And it’s a line of reasoning that makes sense - beyond going completely to voice control, I cannot see myself using any word processor without touching a physical keyboard. And many of the more complex functions of Excel, like formulas and macros, would be near impossible to replicate on a touch-centric UI without neutering a decent amount of the power and control users have.
So, instead of redesigning Office to fit within the new Modern UI guidelines, Microsoft simply ported the x86 version of Office 2013 over to ARM and runs it as a desktop application. I can’t blame them - Office 2013 was redesigned with the Metro design language, so it already fit the Windows RT visual style, and it was just easier for them to not mess with the UI or UX further. But that’s actually a good thing - Office is the killer application for RT because it functions exactly the same as Office 2013 on any other system. If you live in the world of Office 2013 and SkyDrive, this is fantastic news because you need to make almost no adjustments to your workflow. It’s just as capable and powerful on here as it is on any other Windows system.
Office isn’t perfect, and you can level any number of complaints at it - aggravating at times, uses proprietary file formats, resource intensive, expensive, difficult to learn, and I’m only scratching the surface. Based on my usage of the Office 2013 Preview on Windows 7 and RT, it’s actually my favorite version yet, so there’s that, but the main point is that this is still a full-fledged version of Office that we’re talking about here. Over the last two decades, people have learned to put up with its quirks and faults, and it’s still one of the single most important pieces of productivity software on the market.
So, how does it all work? Pretty well, all things considered. All of these applications are pretty much exactly as you would find on an x86 PC, so I’m not going to go very far into the design and functionality, though there are a couple of interesting use-cases that I’ll bring up later on. The most critical concern I had going into Office on ARM was performance - the reputation for being a resource-intensive software suite is not undeserved, let’s put it that way, and quad-core A9, great as it is, doesn’t have the raw compute horsepower of Atom much less Core 2 or any newer Intel processor.
In Word, it’s relatively easy to pull 30% CPU utilization when typing quickly. Anand saw up to 40% on Surface, and I managed to get CPU utilization all the way up to 55% when pressing random keys as quickly as possible. Compare this to Notepad, which usually hovers in the 5-10% CPU utilization range, and it’s clear to see how heavy a load Office puts on the system. Even with the high CPU utilization though, I never saw any lag in the characters appearing, so it’s mostly an interesting point to note and not an issue with the typing experience.
Update: Microsoft shared an official response with us about the high CPU utilization we're seeing:
Increases in CPU utilization while typing are an expected behavior in Word, but should not extend beyond the immediate typing. However, we are always looking at ways to improve CPU utilization and the customer experience with Office.
To really push the system, I loaded up some of the Excel files I work with at my real life job as an automotive technology researcher. These are raw and mostly unprocessed dynamometer data test files, with roughly 3 million data cells each (give or take.) The largest had just under 4 million data cells and was 39MB in size, smallest about 1.8 million and 19MB in size. A couple of graphs and some equations. Together, the four files totaled 112MB. I decided to open all four at once - it took about a minute and a half, with a max CPU load of 72%. It was crazy, but once everything was loaded, performance was actually decent. I wouldn’t want to necessarily work on the files for extended periods with a system like this - the screen is too small, and the couple of bits of lag would drive me nuts (plus, without Matlab, it’s a bit pointless) but for quick graphing of basic data, it works significantly better than expected.
The good thing is that there’s a lot of RAM here - with 2GB seeming to be the default for Windows RT tablets you’re rarely memory starved. So even with 250MB worth of RAM dedicated to Excel, CPU headroom is still the main limiting factor. For more basic Excel tasks, like the chemistry labs that were commonly assigned in undergrad, there’s definitely more than enough power here. The files I loaded up are typically only manipulated on quad-core workstation notebooks and are far and away an extreme use case.
I didn’t really spend a whole lot of time in PowerPoint, because I typically don’t use it very much. I loaded up a presentation I gave late last year about some of my research at the time, and started editing it to see if the experience had anything different to mention. Performance seemed good enough, with maybe a hint of frame drop when scrolling through the slide thumbnails on the right edge (it moves at something closer to 25 FPS than 30). I liked the ability to swipe back and forth between slides when in Presentation mode, that’s one nice thing about the tablet interface. Other than that, this is just PowerPoint on a smaller screen.
OneNote is the one that I was really interested in. Because even though it runs within the framework of the Windows desktop, it’s an application that really lends itself to tablet usage. Back in the tablet PC days, OneNote was the killer usecase, the one program that really lent itself to being used in conjunction with pen-input. I came very close to buying a Wacom-enabled tablet on numerous occasions for the specific purpose of taking electronic lecture notes with OneNote. (It never happened, and I ended up taking very few notes of any kind through college, but such is life.)
Now, without active digitizer support on most Windows RT tablets (I haven’t seen any with active digitizers), you’re limited to either keyboard or capacitive touch input. This is where the handwriting panel comes in, and like I mentioned before, it’s quite good even when you’re just using your finger to write. With a capacitive stylus (which I regrettably do not have on hand) I can see this being legitimately useful to take handwritten notes on. It’s good enough that you can get away without a Wacom-enabled tablet if you don’t want to shell out the extra $400 or so. I genuinely wish something like this was available when I was still in the notetaking phase of college, many moons ago - the fifteen year old me would have killed to have a $600 tablet with solid handwriting recognition, even without an active digitizer.
And that’s really what makes Office for Windows RT interesting. It gives you 95% of the office suite experience and capability of any normal desktop or notebook PC in the modern tablet form factor, introducing some much needed productivity into what was previously a very content-consumption oriented device category.

I just got done fully reading the Surface review. This should be a good one as well.EnzoFX - Thursday, October 25, 2012 - link
Sure was.Win RT is promising, it really is all about the tablet experience. Which is why I don't understand their decision to have the desktop and access to all the underpinnings. Surely a real power user won't limit themseles to RT, and simply go for the 8?
Is it to have developers make desktop-centric arm based apps? That seems counter intuitive. They could have easily made Office into a Modern UI style app. What is the real point in the end? Maybe I missed something.
My only other criticism is little things that sometimes show me lack of focus. 4 edge swipes? Couldn't they have streamlined that down to 2 max? and why must some things just be too hidden, or even not even accessible via the Modern UI?

"Is it to have developers make desktop-centric arm based apps? That seems counter intuitive. They could have easily made Office into a Modern UI style app. What is the real point in the end? Maybe I missed something."Considering developers can't make desktop apps for Windows RT that isnt it...
I'm guessing MS was simply too lazy or "didn't have time" to build a metro equivalent for everything for Windows 8 and will likely continue the work for the next release, as long as the desktop is still there they could also put Office even on RT with minimal effort.
But yea, it's odd.

I am really interested in seeing Windows RT with Quad Core Qualcomm S4 Pro. 40% faster CPU, 100% faster GPU than Tegra 3. Power friendly. It should make RT shine even more. In fact I believe that the APQ8064 was made for Windows RT.karasaj - Friday, October 26, 2012 - link
This is exactly what I was thinking and hoping Surface would have come out with.Krysto - Thursday, October 25, 2012 - link
"The odds of that situation arising seem relatively low, so my bet is that the strength of the ecosystem will be a non-issue a month from now."Really? A month from now? Can I hold you to that? It will be at least a year before Metro store gets even tens of thousands of apps. I think you've been reading too many Microsoft PR statements ready, and it's starting to influence your objectivity, and now you're just using Microsoft's words as your own - while thinking to yourself that they are your own words.

Right... Because you're really going to browse and install 10's of thousands of Apps. (With the majority being fart of flashlight apps anyway.)munsie - Thursday, October 25, 2012 - link
So when it was Windows vs Macs back in the 90s, the argument was always that there were more apps on Windows, why would you buy anything else? But now that there are more iOS apps vs Win RT apps, it's that most of them are "fart of flashflight apps"?More apps isn't just more junky apps -- it means that more experimentation/innovation is happening as well. It means that there are apps being built for the long tail, not just the mass market appeal. Think about apps targeting very specific users, like doctors, lawyers, engineers, etc. These apps aren't the ones you see at the top of the charts, but are the ones that sell platforms.
Microsoft more than any other company should understand what Apple has accomplished with the iOS App Store.

Yes and no though. Developer tools are much better than they were in the 90's.Many of these apps are already cross platform with ios and andriod, and many others already have windows versions or silverlight/wp8/xbox 360 versions that can be ported much easier.
Many of the popular dev tools used by smaller/indie developers already support exporting to different platforms, so if they don't support windows 8 yet, they will soon enough.
Plus Visual Studio is great.
Not to say Apple's accomplishments aren't amazing, they are. Nobody could have envisioned the success they've had in such a short time.
Apps will come. There's no money to be made right now anyways, nobody has devices, it'll all sort itself out in a few months. I think 1 month is optimistic, but within 6 months the apps will be there.
StormyParis - Thursday, October 25, 2012 - link
Well, the 90's argument was "1- why pay more 2- for slower, less expandable hardware that 3- is missing some key apps or even whole categories of apps and 4- is fading", so really, a series of issues.In the present case we get , 1- why pay the same or less 2- for slower, but a lot more expendable hardware that 3- has a killer app, though it's missing many key apps and all of the non-key ones but 4- will probably surge.
BTW... Google "75% Of Apple's App Store Is Ignored by Consumers" for a fun fact, if it is indeed true.
