Is it worth switching to a Mac?
jmtame: I recently made the switch and my #1 objection to doing it: the keyboard shortcuts.  I've actually mastered most of the shortcuts in about 1-2 days.The main reason I made the switch is because I am going to do iPhone app development and that's pretty difficult on a PC.So far it's been pleasant.  I am pretty impressed by OSX, definitely some advantages over XP and this is pretty much understood and repeated, but Apple goes out of their way to make everything work nicely.  My freakin' keyboard lights up when the room gets dark.  That's pretty cool.
