No offense, but are you stupid, or just ignorant? Microsoft's current 64-bit OSes run 32-bit applications (not drivers) fine. Why wouldn't their future 64-bit OSes that don't have a corresponding 32-bit OS?
I recently installed Vista Home Premium x64 and all the apps that run on Vista x84 run on it flawlessly.... even all my hardware has x64 compatible drivers except my webcam at present, apparently they're working on it so I'm not worried about it and can boot into Vista Ultimate 32bit or XP Pro 32bit. So yeah, all this baloney about x64 incompatability is just that, baloney and the fear of change... the refusal to move on and try something different. It's totally illogical but some people will continue to have closed minds, regardless of technological progress making things even better again.
As for Windows 7, it looks pretty darned exciting and I can't wait to try it out when the first public betas are released. I rather like the taskbar/thumbs improvement and the way it handles/deals with windows... very nice and most welcomed.
I must admit though, upon seeing that monitor in the first clip, I did suffer with screenis envy. I recently got myself and the missus a 22" ViewSonic each, and I've been truly happy with mine... 'til now! It'll never be good enough, not now I've seen that rather large 'touchyfeely' monitor in action.
