I've been running Windows 2000 Professional for a long time because the improvements over Windows XP Professional aren't that great in a SOHO enironment. However that will all change when Vista is released. I most pleased with Microsoft embracing Vector graphics vs. bitmaps. I'm looking forward to this OS upgrade. There hasn't been an OS release of this maginitude since we went from DOS to Windows NT. Don't forget that DirectX 10 will only work on Vista. It will also be completely 64 bit operating system (that doesn't mean you'll have to have a 64 bit system to run it thanks to HALs). I'm rambling now.
