Just adding another case of purchasing the upgrade from RP.
I do miss Aero, desktop isn't as ugly as RP, but it is very plain and not in a good way.
Apparently I'll not be using anything Metro since MS can't get their shit together. Even if I use a non admin account Metro won't work with Admin Approval mode disabled. :/ Working without admin approval mode breaks drag and drop, and makes editing system files miserable. It's quite clear MS isn't targeting professional devs. Oh and LOL at DevStudio 2010 not being compatible, not surprising but pretty lazy from a company that used to be very pro developer.
Start8 works pretty well, unfortunately it isn't as smart as Win7 start menu, where Win+R was superfluous. I can live with it though, it is miles better than Metro for starting tasks and plays nice with RDP and logmein.
Had it all blow up with a VIDEO_TDR_FAILURE, but that hasn't repeated, could just be a funky install issue.
