I won't be using Windows 7 then, in fact I'll continue to stick with XP. The 'old' taskbar works perfectly and these new changes are for change's sake only, something different to try and justify the existence of another Windows release. Much like many of the 'features' in Vista which were a step backwards from XP.
Did they not say it is apparently more touch screen friendly?
I'm not so keen on the new task bar, I do like its more squareness if you know what I mean, seems allot more clean, but I don't like the fact it is taller than the older task bar and the way tabs are displayed on it, if it was the same old task bar but just a cleaner looking more square look then that would be good for me.

Seriously.
