Which is better: Mac OS X or Windows Vista?

I would have to say Mac OS X is a lot better, with Mac OS X you can run XP or Vista while you are using Mac OS X.

In my opinion, Mac OS X is far superior to Windows Vista, unless you are using Windows-only software or you are a gamer. Although there is a growing amount of Mac OS X support, you may encounter some problems when switching operating systems. Mac OS looks better and similar to Windows Vista, but it is alot more memory efficient and does not require the newest software to run. Remember, Mac OS X has been around since 2001. Although there are several new security features in Vista, many users will find them a hassle and will probably just turn them off. Therefore, I believe that Mac OS X is better, but you should pick the operating system that better suits your needs.
