Do macs come with a mouse with more than one button yet?
Technically speaking, yes.
Mac's are kinda weird. No right clicking!
I right click all the time! It's not like the OS isn't built with right clicking support or USB mouse support.
I hate that. Renaming files and saving pictures is such a pain in the ass. 
No it's not. You either right click, or control click. Or in the case of pictures you just drag them from the website to a folder.
If you're not a PC gamer then the choice comes down to your price range, and preference of operating system. Using 10 year old crap like right licking as a determining factor is silly and ignorant. As a computer science major and someone in an operating systems class I say both Windows XP and OS X are good operating systems with their own unique design flaws and decisions. It all comes down to style and usage habits.
Also a Mac has and always will be a PC. It's a personal computer, its a pc. The CPUs are even the same now, hey we can compare ISA in a meaningful way finally!
