When the first bits of information came out about Windows 8 having an additional user interface just for tablets, inspired by Windows Phone 7, I always assumed we'd be seeing a separate, tablet-oriented version of Windows NT for both ARM and x86. Today though, Microsoft's Steven Sinofsky, and the ever awesome Julie-Larson Green unveiled that there will be one version of Windows, and it'll have both the new tablet interface, as well as the classic Windows interface just for those applications that need it. However, the tablet user interface is not a mere layer - it's all a bit... Weird, really.
Look at this video of it, and you'll understand. Look what happens when they show Microsoft Office. Other things to look out for: how it handles multitasking. I have to say - pretty damn awesome.
As you can see, the old Windows desktop kind of becomes part of the classic application, integrated into what I would reluctantly call its 'window'. It's kind of odd and jarring, but at the same time, I kind of get the idea that Microsoft is pulling a UAC on third party developers - UAC was designed to be annoying so that application developers would clean up their code. This jarring classic application handling? The exact same thing. Do you really want your application to be labelled as 'classic' and look like that?
Sinofsky was also asked if OEMs could forgo the classic interface altogether, and the answer was - "just don't use any desktop applications". My understanding is that Windows 8 is taking the first steps towards obsoleting the current Windows start menu/etc. paradigm. In these demos, it's already something that's relegated to classic applications alone; it doesn't seem to be possible to 'minimise' the new UI and reveal the classic desktop, nor does it seem to be possible to call up the classic desktop as an application. It looks like it's part of classic applications.
Interestingly, the new interface, and its applications, are touch-optimised (clearly), but they work equally well with a keyboard and mouse, according to Microsoft. Being a Windows Phone 7 user myself, and a devout admirer of Metro, this new interface jiggles in all the right places, but I do doubt this whole talk of 'optimised for touch, works equally well with mouse and keyboard'. Of course, this user interface is spearheaded by Larson-Green (the driving force behind Office 2007 and Windows 7's user interfaces, and thus, the best thing to have happened to Microsoft since, well, forever), but still.
As far as system requirements go, Sinofsky stated that Windows 8 will, once again, lower the system requirements compared to the previous version. Windows 7 was already lighter than Vista, and now Windows 8 will be lighter than Windows 7. I tip my hat to Microsoft for that one - but at the same time, they didn't really have a choice here since it'll have to run on tablets and other constrained devices.
Another question: what about a transition path from Windows x86 to Windows ARM? Well - there isn't one. No virtualisation or other compatibility layers. You'll just have to suck it. This gets a big thumbs up from me.
That's about everything I could gather from the Engadget liveblog. Sinfosky did talk about Windows NT, but not being interested in the nitty gritty like we are, Engadget skipped over it (bad Engadget! Bad Engadget!). Hopefully that part will be shown in videos on the D9 website over the coming days.
Now, bed. Bye!
