Windows 8 Metro interface is cool. There are some things about it I *really* like some things that are better than Apple's implementation. However, all those things hinge on abandoning almost everything MS Windows has stood for/supported in the past. MS knows that to move forward it MUST now reinvent itself. Apple knows this too and we see that in Lion's idiosyncrasies. One thing that stuck out to me when I started watching this video ( http://video.ch9.ms/build/2011/mp4/BigPicture-1.mp4 ) is that Apple's advantage is the iOS penetration (in particular the iPad) MS's advantage is their massive installed base of existing Wintel hardware. However that hardware will not really take advantage of Metro (as I see it now). Microsoft is betting the farm on that existing base but if they are wrong and the installed base isn't enough momentum to stay with MS this could/will be the mass migration. The same thing is happening with FCPX, although to Apple's disadvantage. Moving to FCPX means relearning a new system so why not learn another competitors system if you like it better? The problem with FCPX is it gave people an opportunity to switch which is what I see Metro/Win8 as doing. I think Apple should follow Adobe/Avid's example and do a mass "buy back" of old PC's on the release of Win8. With their healthy margins they could probably do it and only bleed a little bit of money while gaining exponential market share. What do you guys thing?
