Up to you! I tried it at work for a few days (TechNet RTM version) and I detested it to the point that I really loved being able to re-format my PC and put Windows 7 back on.
To be honest, I saw it as an OS that had lots of promise and some very nice features (really). But there's a few things about it which spoil it for me. Being forced to use Metro (unless you install third party apps), the fact that Search no longer searches the Control Panel, the awful full-screen view of Metro apps (like the built-in PDF handling) which means you can no longer snap multiple Metro apps side-by-side with other apps.
Yeah, it's got promise and I can see the point of the Metro start screen, but for me it's a bit like Vista. Some promising ideas and improvements, but too much poor and inconsistent execution. I'll wait for them to fix things properly for Windows 9 before moving away from Windows 7 methinks.
