Early thoughts about Metro in W8 Preview vs TLB in W7

I've tried the Windows 8 and the new Metro interface. The Metro interface is good, but for tablet PC's with the touch screens or on the media centers. Using Metro on the desktops with mouse is very hard (I even don't find the shutdown button hock: ). The good news is there are the same desktop as in Windows 7, and TLB is working fine there. I don't think that MS switch all W8 desktop computers into the Metro interface in the final release, so TLB will outlive the Windows 8
