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.

    Think you hang out with a lot of kids, cause everyone I know doesn't promote games. They promote useful apps. Cardstar, vehicle traffic apps, gas prices around you apps, etc. Well, at least what I saw in the DC/Baltimore area.

    Maybe in middle-of-nowhere, where there is barely any traffic, 1 supermarket, 3 gas stations, they don't need such apps and just play games.

    Well, I guess you hang out with middle age people who drive gas guzzlers and trucks then. See what I did there, dick?

    Just take a look at the Apple App Store charts, mostly games and entertainment apps rule. Do some reading. It's not just coincidence that Angry Birds, Fruit Ninja, etc., became household names.

    Oh and try to argue without insulting or degrading others. You may not be a kid but you should grow up.

    yeah this was never true, even for android and ios. it was a rumor started by....wait for it, wait for it..............

    Microsoft.

    You ARE aware that Apple stopped accepting fart apps back in September of 2010... over 2 years (and 500,000 apps later), are you not?

    I find that disappointing.
  • cappasay - Thursday, October 25, 2012 - link

    Yesterday the latest report said 7k apps. I can't attest to their quality.. but your statement about taking "at least a year" for "tens of thousands of apps" seems a bit off.
  • p05esto - Thursday, October 25, 2012 - link

    How many stupid apps do you actualyl use? I installed about 20 apps when I first got my tablet and have hardly installed anything else. I surf the web mostly, check a little email and play checkers....that's about it!

    I also think the review is being overly optimistic about Metro apps.

    The argument is that Windows 8 will have a huge install base, therefore developers will write Metro apps for Windows 8. But the review itself admits "for mouse-based navigation, you’re better off treating it as a glorified Start menu", and indeed the 'traditionalist' reply to Win8 critics seems to be "other than the Start screen, you can ignore Metro and just use it like you used Win7." If this is the way people are going to use it, the installed base argument is worthless; all those supposed millions of Windows 8 users are going to be in desktop mode, so there's no incentive to write Metro apps for them.

    Metro app development is going to have to rise or fall on the strength of the tablet market, which is a much iffier prospect.

    I expect to see the market split between power users / IT workers and consumers.

    Professionals requiring the heavyweight software packages (MatLab, Maya, Photoshop, etc) will probably stick with the view that the start screen is nothing but a glorified app launcher.

    After an adaptation period however, consumers will find themselves using Metro more and more often and at some point, desktop mode will become irrelevant for many, including those with laptop and desktop PC's. So I do think notebook/desktop sales will help strengthen the market for Metro app developers.
