Why the change of heart? I love my mac it's faster than vista by a long shot I have both installed on my computer. I heard windows 7 is better but i haven't installed it yet. Also mac is much better for developer programs like the adobe suite.

LOL! Macs are awesome. Once you get used to the operating system, nothing else compares. Anything you need to do is already built in so no need in buying all this crap software. Such as mounting discs, partitioning harddrives... its all so easy
