I switched to Mac back in September. In December I realized that I hadn't turned my PC on since the day after I installed my Mac so now my PC is in the basement.
I was running a beta version of Vista under Parallels on my Mac. I've always been an early adopter when it comes to Windows upgrades since it's my job to keep up with systems. I have never been so uninterested in a Microsoft upgrade. It just feels like pure bloat to me. Why does better security and a pretty interface have to translate into such a pig?
I migrated from Windows 2000 to XP without upgrading a single piece of hardware and everything worked. To go to Vista I would pretty much need a completely new PC. No thanks.
