I'm putting this in Soapbox because I could easily see this getting out of hand and become a debate.
Please don't take this reply as an attack on Macs. I like Macs. They're built off Unix, which I like a lot. I usually bring up the shell on those computers and just run everything from there. The user interface is pretty and the whole computer is easy to use, with most applications running very well and smoothly. It's more efficient as an OS, and now has the ability to run XP on top of it for more specific needs.
But with that out of the way; be very careful with them. Especially if you're going to be running Firefox. It's important to realise that Macs are NOT as secure as they once were. Mac is starting to suffer from the same problems windows had and learned to deal with. It's still mostly safe against viruses and certain trojans (unless the user himself plays a role in the installation of it, the best virus is the user himself), but it is easy as HELL to hack.
Thankfully people aren't prone to do hack Macs. They're just not a common target. But just to be safe, it is usually recommended to continue using Safari, or even better Chrome.

There are also a whole lot more serious vulnerabilities in Macs. That's normal though, since they haven't been making popular operating systems as long as Microsoft has. Microsoft is just more used to dealing with hackers trying to break their system.
