PC has come to mean Windows Operating System, not Personal Computer anymore. Anyway, steam is adding mac support so I don't care anymore. Blockland runs on Mac, Steam will run on mac, that's all I need.
I heard that about steam, but I think it will probably be a let down. Steam is just a content delivery system, which basically means all it does is download the games and authorizes you to use them. Which means every game will have to be workable with MAC, which every game isn't at this point. So steam itself will work, but not all the games. Which means that mac users will still have to wait a while for the games to be ported to their system. Sorry mac users, you still cant win.
Macs are a IT nightmare also. Windows usually works the best with networking and servers, other than Linux/Unix of course.
Oh, and too whomever said that macs are basically Linux, mac os is based off of Unix, and Linux was developed along the lines of Unix, but has major differences from it.
