I have Windows 7, and I actually like it. It runs really well on my computer. I haven't had major problems with it yet. DirectX is a great API for developers. If Commodore would have actually marketed the Amiga API when it had the chance, maybe C= wouldn't have gone bankrupt so soon. By what I've read of the Amiga API code, it looks pretty easy, but it's not promoted. The only Mac I would buy would be a Mac Mini with OS X Server so that I could have unlimited user accounts for cheaper than what Microsoft charges.
