Microsoft Details Windows 8 for ARM

MrSeb writes "In an 8,000-word treatise, Steven Sinofksy himself has taken up pen and paper to describe Windows 8 on ARM (WOA) in great detail. There's a lot of good stuff in there, but one point is particularly troubling. Quoting Sinofsky: 'WOA does not support running, emulating, or porting existing x86/64 desktop apps. Code that uses only system or OS services from WinRT can be used within an app and distributed through the Windows Store for both WOA and x86/64. Consumers obtain all [WOA] software, including device drivers, through the Windows Store and Microsoft Update or Windows Update.' It's hard to under-emphasize just how huge a change that is. It's one thing to say that ARM CPUs won't support x86 emulation; something else entirely to split software delivery and installation. Up until now, one of the biggest differences between desktop and mobile operating systems has been the ability to install software. It's true that Microsoft's decision to wall off unapproved software installation is similar to the approach of Android and iOS — but iOS isn't the same thing as OS X. Combining both of these decisions under the 'Windows' brand could be disastrous, not because Microsoft is evil, but because it creates two entirely different user experiences on the basis of which ISA your CPU supports."

      There is another possibility: Microsoft has massive legacy commitments. Practically all the world's boring corporate stuff that isn't old, specialized, or hip, enough to be running on some sort of intimidating big iron or linux/web/cloud/thingamawhatsit. Most of that software is absolute dreck, and rather boring, but much of it is also quite critical to a variety of high value operations and impossible or uneconomic to port or even modify very much. For this reason, Microsoft's walled-garden options on x86/64 are pretty minimal. Architecturally they could roll it out tomorrow(Software Restriction Policies are basically that, but under the control of your domain admin); but the customers that matter would scream like nobody's business.

      However, since there isn't any legacy Windows software or legacy Windows device drivers, on ARM, since it has never run on ARM before, there is no legacy market to worry about. Microsoft has a free hand, more or less. As with the xbox, the other recent situation where MS started clean, without legacy impediments, they apparently see a walled garden as their best option.

      It remains to be seen how long the momentum of more-or-less-open x86 IBM compatibles will carry them into the future; but so long as the legacy/in-house/custom demand is there, they'll be hard to kill entirely.

      I don't think the in-house and custom software is going to save anything, because the large majority of new business applications have the application itself running in the data center and the users access it through a web interface. And legacy software is replaced by new stuff the more time passes.

      But I don't think the future is as bleak as all that, for different reasons. The largest impetus for closed platforms comes from the wireless carriers who want to make sure you aren't doing anything as unscrupulous as making a VOIP phone call over WiFi without paying them for minutes, and who subsidize your phone and in so doing become the "customer" of the device who gets to decide how open it is.

      Here's the thing: I expect that inside of five years, flip phones are going to be almost completely dead. Tomorrow's top end Android handsets will still be ~$500, but today's will be $50. Some handset maker who still has a tooled factory churning out "obsolete" phones will realize that with nothing more than a software patch, they can sell them retail as WiFi-only devices that still make phone calls and browse the 'net as long as you're at work, at home, at school or anywhere else that has WiFi. The poorest customers will quickly realize that $50 or $100 once is much less expensive than $50/month indefinitely, even if it means they can't make calls in their cars, and many will do that. The carriers will then realize they're getting $0/month from these customers and that if they offered a cheap bring-your-own-device plan, they could be making $20 or $30/month from customers who by and large don't actually tax the cellular network because they use WiFi 90% of the time, and a big chunk of those people will pay that so their phones will work in their cars etc. And so will a big chunk of the people who had been buying subsidized phones, who realize that $500 once + $30/month is a lot cheaper than $200 once + $100/month. (The savings for everyone comes from the fact that you're taking a massive load off of the cell towers and putting it on DSL and cable lines where adding bandwidth doesn't require outbidding everyone else for finite wireless spectrum.)

      With any luck that will be the end of carrier device subsidies and with it the end of locked boot loaders etc. Even the carriers seem to be looking for a way out of subsidizing premium devices for most of their customers. But do that and you open the door back up for innovation: Once people no longer need carrier approval to sell Android and other Linux-based devices that work away from home, you have the possibility of things like the Spark tablet or whatever Canonical feels like producing start to take hold, which can easily be made to run both Android apps and Linux native apps, and you can see the possibility of an open platform gaining a sigificant foothold. Not to mention whatever products come out of Google buying Motorola Mobility.

      If that happens then Microsoft will have to decide whether to go the Apple route and try to keep their ARM platform closed, or stick with their traditional forte and open it up. And I kind of feel like there isn't any room in the market for more than one Apple.

  5. Chicken and Egg problem by DickBreath · · Score: 4, Insightful

    The value of Windows is the huge legacy software collection that it runs.

    A "windows" platform that cannot run that software base is basically a new platform. Starting from scratch. Sort of like a new version of Linux, or Hurd, or something new.

    Microsoft may port their own apps. Great. But what about third parties?

    There is .NET, of course. But apps written in .NET would be fairly new apps. What about apps written in older languages? Some apps may be trivially recompiled. Or recompiled after significant effort. But some apps may be slightly or even deeply wedded to the x86 and maybe x64 architectures.

    Other apps may be wedded to legacy languages that may not get ported. Will Microsoft be porting Visual Basic 6? Visual FoxPro? What about Delphi? Etc.

    Even if a developer can fairly trivially build their app for WOA, why would they if there is not a large user base on that platform ready to fork over money? The developer has to expend effort (eg cost) today on a platform where customer demand may not materialize. If WOA doesn't run an end user's favorite legacy applications, then why would the user want to migrate to WOA? It's cheap and easy to buy a desktop or laptop running legacy Windows that is familiar and runs your legacy apps.

    WOA has a chicken and egg problem. Which came first? The large number of third party apps / developers supporting WOA? Or the large end user base running WOA?

    Furthermore, a developer who expends effort to port their product to WOA, even if "porting" is little more than a trivial recompile and repackaging, and tracking new SKU's, that developer will want to be compensated for that additional effort. You can bet that developer will want top dollar (eg price gouging) for that new WOA edition of their product. Do you really think you'll see a $99 Photoshop on WOA? Also don't expect a free upgrade to the WOA edition of your current application.

    WOA may be Microsoft's counterpart of the PS/2 moment. The market may "just say no" (as they say in the '80's). The problem with PS/2 was that it was nothing more than an attempt to recapture IBM's monopoly using a new platform. That is what WOA is. Microsoft wants their legacy monopoly on these new mobile ARM platforms, just as IBM wanted their legacy mainframe monopoly in the PC market.

    Another problem is that these new platforms are fundamentally different. They bring things that legacy PC's don't have deeply baked into the system and applications. Android for example can support both the legacy keyboard / mouse setup as well as touchscreen and voice commands. Those pesky new PC's offered a lot more than a mainframe terminal had, such as mouse and GUI. Oh, and cheap software, just as the new platform app stores offer pretty cheap apps.

Locking down software to approved sources only, and getting rid of creakingly old APIs that date back to Windows 3.1, will make it faster, more stable, and more secure - but now people are complaining.

    Exactly. It's legacy software that's tied mainstream computing to the x86 architecture for two decades. Tthe x86 is a power-hungry architecture best suited for desktop and rack computing, but recent trends are towards mobile computing. Laptops started to outsell desktops. Netbooks hit the market. Smartphones reached a level where they could be used as complete computers. And the Tablet PC concept, which had been bubbling under for over a decade, finally found it's niche as a "maxi-smartphone". x86 is dead, and MS need to encourage people to produce standardised, architecture-neutral code if they're going to migrate to another architecture.

    If they don't migrate to another architecture, what happens? Smartphones with HDMI out (and a built-in focus-free laset picoprojector) and Bluetooth or USB for keyboards and mice displace the traditional computer. If Windows is still split between phone and desktop, Windows dies.

    So why the separation between desktop and phone OS? Why WOA an not just maintain their ARM version as Windows Phone? Because right now, phone apps are phone apps, and desktop apps are desktop apps. An OS lives and dies on its third party software, and this move is calculated to ensure that there is a back catalogue of desktop software available when the two paradigms merge.
