I have an old mac laptop and a gaming PC. Mac is nice in that you can get along with pretty much only buying MS Office, the quicktime upgrade (Pro or Plus, i dont remember what its called. Regardless, it lets you use teh camera to record video and opens up video editing options) and no other software and still have a relatively good system for creative purposes. I also just like the operating system more. I hate vista with a passion, i've kept my PC on windows XP and i intend to do so until I'm forced out of it. Never seen a windows 7 computer so can't comment much on that. But I do feel safer on the mac, mainly because there just arent that many mac-focused viruses out there because PCs are a much bigger market. It's cleaner looking than windows has ever been, but it has a low customization level. I like having both though, the mac laptop/windows desktop works well.
