I used to be deathly opposed to Macs for one reason: Mac Fanboys.
Anyway, I got my first Mac just over a week ago, and have only one thing to say:
I can't believe I didn't make the switch earlier.
It only took about 2-3 days to figure everything out (as a first-time Mac user) to the point where I feel comfortable doing anything on my Mac that I've done in Windows. Seriously though, EVERYTHING is so much easier, it's absolutely ridiculous.
Most program installations simply involve a drag and drop, no registry or weird setups.
Yesterday, it took my Mac LESS time to locate and install my printer WIRELESSLY, then proceed to print something than it did for my PC laptop to finish loading my desktop.
OSX 'magically' found my printer and within seconds it was ready to use. You know what I had to do in Windows? Go through several tedious steps which involved me downloading and installing drivers, an HP utility which somehow installed itself and starts automatically on startup, and a completely unnecessary reboot. You know what happened under OSX? IT JUST WORKED.
It really doesn't take that long to get used to it. The functions in OSX are a lot more accessible compared to windows, which tends to hide things. I have a barebone version of XP in parallels and windows 7 in boot camp JUST in case, but to this point I've never had to actually use either since I was able to find OSX versions of all my programs.
I know I haven't been using OSX for very long, but as a lifetime Windows user I can honestly say I've started appreciating OSX more and more. It's like they made an OS for humans. Make the right choice and buy a Mac. You won't regret it.
