Am I the only one who actually thinks the Metro style looks quite nice (considering tablets/phones)? I like it. Can't say how well I'd like it on a PC though. Think I'll stick with 7.
I think it is vastly superior to the UI on Apple's mobile devices. I have an iPod touch and there's an iPad somewhere around my house not owned by me, and I can't say I care much for either of them. Metro looks very simplistic, innovative, and colorful as always against Apple's fascination with the color gray. It's a very useful interface for tablets and smartphones.
On a PC, however, I don't think a touch-first interface could be very useful or innovative. It seems like a step in the wrong direction. The whole point of having a PC is that you can use it however you like, yet the Metro interface seems like Microsoft telling its consumers that they should use their computers a certain way. As Defron put it, the interface promotes consumption. You browse the web. You view videos. You sort your pictures. You buy lightweight apps to pass the time. There's not much in terms of production value which is what businesses are looking for (businesses, mind you, are the biggest source of Windows sales). In fact, I found it rather hilarious that the one moment they showed something productive in that demonstration, it required jumping into the Windows 7 "ghetto" because it isn't designed to work with Metro. It was Office, no less, Microsoft's own product. And it doesn't even work with the interface that they want to be used for everything.
The only production program that I think a touch-first interface could benefit is Photoshop. If you write that primarily for the tablets, it could help artists by removing the medium through which you draw, the drawing tablets that lack screens. I can attest to the fact that it is easier to draw when you can see what you are drawing and where you are drawing. When you don't have a drawing tablet with a screen, it takes some time to learn how to assume where your hand is. And now these Windows tablets will simply be eliminating the need for an external tablet device.
Windows 8 is coming out? When? Windows 7 just came out. The only reason I have it is because when I first bought my laptop, (wich came with Vista) everyone who bought a PC at theat time was getting Windows 7 upgrade for free. So will we get the same upgrade for free or have to pay for it? I don't like the idea of buying a new OS every 2 or 3 years. Is this the new way things are going to be now?
I guess it will technically be 3 years by the time it actually hits shelves. The 3-year release cycle is actually pretty standard. Apple updates their OS about every 18 months, and popular Linux distributions are released in even shorter increments. In fact, XP is the single exception to the 3-year cycle. I guess it is still fresh in everyone's minds, and people assume often that Windows 7 was only released so quickly after Vista because Vista was bad. So in fact, if you even consider the 3-year cycle as what to expect from now on, Microsoft is still the slow turtle of OS releases. And don't even get me started on Web Browsers

What's the point in Windows without legacy software? (this is also why I see Windows on ARM as useless)
It's only 50 or so million lines of code, that's not significantly more than Windows XP and is significantly less than most Linux distros (of course Linux distros can do a lot more)
It's nice to continue supporting the same features, but I hear that a lot of old code is simply in need of updating. Programs written back in the day that have simply gathered dust and become buried underneath newer code, and forgotten. I think it'd be nice to continue supporting as many features as you can, but a lot of people out there really want Microsoft to clean up a lot of the excess code they have (which could probably be streamlined if they put the effort in).
Looks like I'll continue to use XP.

Vista is horrid.
Get 7. It's really nice, and I recommend it to everyone. I suppose that's why people are upset right now, because Windows 8 threatens to ruin everything people liked about 7. Worse than going from XP to vista at least, because at least Windows 7 was
good. XP, at this stage, is like an old prosttute - really ugly with age and full of viruses.
