Don't forget the constant peer pressure and lame jokes from your coworkers! Oh and if you're a Mac newbie, be prepared to figure it out for yourself. Not that people are unhelpful but that they genuinely don't know any other workflows beyond their cloistered little OS with a barely-usable kernel.

It's hard enough already to not get ridiculed for using JS on the backend from the Java devs :)

Took me a week or so to get used to Mac. I can't care less about what OS I'm using, they all excel and suck in different ways.

Perhaps they aren't particularly font of you calling their OS unusable.
