Bridging the Gap, the Dichotomy of Windows RT
by Anand Shimpi
I described Windows RT as being a tablet OS with all of the underlying Windows-ness of Windows. You can get the big full screen app experience in tablet mode, but poke around your file system with Explorer or use Office 2013 like you would on a traditional notebook if you want to. If the two sides of Windows RT remained fairly separate that’d be one thing, unfortunately there are some dependencies between the two sides of the OS that keep the overall user experience from being as friendly as it is in iOS. There are still occasional reminders that you’re dealing with something that’s distinctly Windows here.
Most mobile OSes have done their best to hide the underlying file system and shell from the end user. Microsoft did, in my opinion, the smart thing and avoided hiding its roots with Windows RT. Although the new Start Screen is the default UI for Windows RT, there’s a big desktop tile front and center that will take you back to something far more familiar:
Unlike the Windows 8 desktop, you’re pretty limited in what you can do here. The only applications that are allowed to run in desktop mode under Windows RT are Explorer, IE10, Office 2013 and the command prompt (there are also all of the Windows specific tools and settings which I’ll get to shortly). Developers cannot make applications for Windows RT desktop mode and you can’t sideload anything here. Microsoft’s belief is that by completely locking down the system, requiring that applications only come from the Windows Store, it can avoid the pitfalls of viruses and malware that can plague Windows machines today.
Steve Sinofsky famously quoted an analyst when they asked if Windows RT would be backwards compatible with all of the legacy Windows viruses and spyware. The answer was an astounding no, and this is exactly why we can’t have open season on Windows RT desktop development. There’s also the obvious financial angle to all of this. Microsoft takes a cut of any apps sold through the Windows Store.
Coming from the perspective of a traditional Windows user, the lack of flexibility on the desktop seems wrong. From the perspective of the rest of the ARM based tablet space, it’s not a big deal. At least Windows RT gives you direct, first party access to the file system. There’s very little exposed through iOS, and with Android you need to download a third party app to get access to the file system.
Explorer works just as it would on a Windows 8 PC. The folder structure is exactly as you would expect it on any Windows machine. There are even some x86 remnants in the Windows RT install such as a C:\Windows\SysWOW64 directory complete with x86 binaries inside that obviously won’t run on your Windows RT tablet.
Internet Explorer in desktop mode works just like a traditional IE windows application would work. The desktop app actually controls settings and features for the Metro...err...fancy IE10. For example, if you want to change security settings, clear your history or empty your cache, you have to do all of these things from the IE10 desktop application. Fancy IE10 doesn’t expose them.
The command prompt is, well, a command prompt. It features all of the same commands that you could run before, although once again you can’t simply drop an x86 exe on your system and run it. Not having binary compatibility can be frustrating at times.
Although developers can’t build applications for Windows RT’s desktop, you can write and execute batch files. Keep in mind that if your batch file needs any additional support files (e.g. sleep.exe) you’ll need ARM versions of them which, unless they come from Microsoft, just isn’t happening.
As I mentioned earlier, there are a few other things you can run and do in RT’s desktop mode. Control Panel, event viewer, disk management and all of the other administrative tools that you’d expect to come with Windows are present in Windows RT (including regedit). There are also the little apps that Microsoft has always included, which also work in desktop mode (e.g. mspaint, calc, notepad, etc...)
Ultimately Windows RT is an ARM version of Windows with tablet makeup on. You still get all of the normal bits and pieces of Windows, minus some flexibility and of course, backwards compatibility.
For years we’ve been asking Microsoft to make a clean break with its legacy code and introduce a version of Windows that was built from scratch, with only support for the latest hardware. With Windows RT, Microsoft finally delivered some of that, but in a sort of weird, backwards way.
As Windows RT only supports the ARMv7 instruction set architecture, none of your old x86 applications will run on the platform. Microsoft hoped to avoid this being a problem by shipping an ARM version of Office 2013 Home & Student Edition with Windows RT tablets, and by directing users at the Windows Store for the rest of their application needs. Although it would’ve been possible for Microsoft to enable x86 compatibility through emulation or binary translation, performance would’ve likely been pretty bad.
The loss of backwards compatibility with years of Windows applications feels wrong, but from Microsoft's perspective you don't get that with iOS and Android so there's no real competitive disadvantage here. Why bother with an ARM based version of Windows to begin with? To bring competition to Intel and ensure that it will be able to deliver Windows to the new wave of ultra mobile devices (e.g. tablets). Intel hasn't been competitive on power or pricing at the low end (read: Atom) of the spectrum for years now. The introduction of Windows RT changed that. Atom Z2760 (Clovertrail) is around half the price of the cheapest Atom CPU of the past five years, and it's price competitive with solutions from Qualcomm. We have Windows RT to thank for that. Without pressure from ARM, Clovertrail would've started around $50 per chip just like Intel's low end parts had in the past. As AMD is no longer a pricing check for Intel in some of these new markets, Microsoft had to look for a new way to offer balance. Supporting ARM is its way of doing that. Until there's a new pricing/power/performance x86 competitor to Intel in tablets, ARM and Windows RT will remain.

I forgot about the base 10 versus base 2 conversion, which affects every single device of any kind out there (no one headline advertises base 2 sizes), but that still leaves over 4GB 'missing' even before the OS install. 4GB is a lot of non-video media or space for apps (I imagine app size is comarable to other ARM OSes because of Windows Phone.)Perhaps that's why we're seeing such memory sizes and pricing for Windows tablets, to make them comparable to other OSes, but companies can put flash for the same price in other tablets as well. Maybe they will and just enjoy better margins, or maybe they will and just price them lower.

One of the things that's held me back from buying an Xbox is that it's $5/month to be a member of their community, so that you can chat with friends, have trophies saved, play multiplayer games, etc. As opposed to free with the Playstation Network, for example.Is there any kind of implicit tax like that in order to use this as a gaming device? If you don't have an Xbox and don't join any such paywall-portal, do you lose access to any games, or capability within any games you do have?

You will never install anything on RT that is not Microsoft approved and they will get a cut of the money too. Unsigned apps cannot be installed on RT - and only apps sold specifically to YOU on the MS App store are signed.But no, there won't be a monthly fee just to have a Surface tablet. The apps you want to run might...

Uh... "you can chat with friends, have trophies saved" even without Xbox Live Gold. In other words, it is free. You only need to pay to play in multiplayer.aepxc - Thursday, October 25, 2012 - link
The review seems to indicate that Windows RT is an OS for desktop computing, but with a touch layer. But what does touch add to desktop computing? In what situations would a Windows RT tablet be preferable to a Windows 7 ultrabook? Or is it just a question of a Windows RT device being cheaper (especially taking into account the bundled Office) by much more than it is worse?VivekGowri - Thursday, October 25, 2012 - link
No? It's an OS for touch computing, with the traditional desktop layer underneath. I tried to spell that out as clearly as possible in the conclusion.aepxc - Thursday, October 25, 2012 - link
That's the argument that I did not really understand. To me, the clearest distinction between computing pre-Android/iOS and the computing those OSs have now enabled, lies not in how you do things (with gestures and touch) but in what you do. I used "desktop computing" in my initial post in the sense of activities one would do at a desk, to the exclusion of the outside environment. Android and iOS ('mobile', 'post-PC', whatever) seem to me to instead focus on tasks that augment one's environment. Google Now or the iPad's use as a flight bag, or Kindle's textbooks (or even messaging services that are more SMS than IRC in spirit) would, to me, be emblematic of the new approach.What you praise WinRT for -- multitasking, (computer-centric) productivity, etc. would to me be very 'desktop' (again, in the sense above) centred. Given that, they are already very well (IMHO, better) served by Win7. Hence my original question -- what does touch (especially at the expense of lower power and a smaller screen) bring to the game? What does it do better than an ultrabook?

Having used the Windows 8 beta on an Asus EP121 tablet, I can attest to what Vivek is saying. To me Windows 8 (any version) on a tablet, at a minimum, extends the capability of what we might call the 'traditional' tablet (e.g., iPad, Andriod) by allowing me to use it effectively for productivity apps like Office. Trying to write long e-mails, online posts, word docs, etc. on an iPad, for example, is an exercise in extreme frustration to me. No such issue on Win8.So to me Windows RT offers an expanded tablet experience, if you will, and full-blown Windows 8 on a powerful tablet allows me to ditch all of my other tablets and notebooks in favor of a single device. A Haswell version of something like the Asus Transformer Book is what I'll be waiting for.

"Trying to write long e-mails, online posts, word docs, etc. on an iPad, for example, is an exercise in extreme frustration to me."And why are the same not any issue on Windows RT? Because you connected a hardware keyboard?
Then why not do the same with an iPad?

Well for starters (imo), battery life and portability. Find a 600$ ultrabook constructed as well as surface. You won't. Many people have given it the same quality as Apple's products.You can't compare things one to one and expect something reasonable. In a world where surface and ultrabooks are the only things that exist, and specs are all that matters, yes, ultrabooks come out on top.
Look at the ipad though. Sure, it has apps. But x86 has WAY more. x86 is WAY more powerful. But more people buy the iPad than many windows computers. Tablets (despite being low power) are cannibalizing the PC market. Why is this?
All day battery life, family friendly media consumption, etc. Sure, an ultrabook does all of this - so why doesn't it sell as well? Tablets have a certain appeal - being able to sit in bed and lay on your side and watch netflix without worrying about a keyboard for example. Having 10+ hours of battery life while internet browsing (many notebooks, even ultrabooks, achieve half that).
Now look at Surface. Don't compare it JUST to an ultrabook. Do both. It's bringing a level of productivity to tablets that never existed. I (as a student) can take Surface and take notes with it in class on Office, and watch movies in bed with it. Tablet's have an appeal because they excel at their tasks - media consumption and (now) basic productivity. You don't *need* more power for those things. If you have more complex needs, then of course you need a laptop.
But if all you do is Netflix, office, and the occasional game, + internet browsing, (me), there's no difference. Surface can do all that and be more or less just as smooth. Applications might take longer to load, but that's a one time thing that can even be improved with software optimization. I have a desktop for more powerful needs (gaming, programming).
PCs have always been more powerful, but their sales are declining. That's because the average consumer (a media consumer, not a power user) puts more emphasis on portability than having a quad core i7 - they don't need that much power.
