Currently I'm using Vista 64, which I regret, however I can't justify spending $150.00 on Windows 7. The first computer my family had was an Apple IIe, the first Windows OS computer we had was a Tandy 386 with Windows 3.1. I still miss the days of being able to exit windows and boot to DOS though, or even bypass the Windows bootup entirely. When you only have a 200mb hard drive, Windows wastes precious space. With every new iteration of Windows it just seems to become increasingly idiot-proof and bloated. The first time I booted up Vista I felt like a foam helmet dropped onto my head and my walls suddenly became encased in soft padding, not to mention that my Windows folder takes up almost 30gb of hard drive space.
