1. Macs are easy to configure unless you're retarded. You shouldn't have any trouble installing RAM, putting in a new hard drive, putting in an expansion card, or anything like that on your own unless you don't know how to use a computer. You don't need to see a "Genius" unless you don't know how to do something or you're doing something risky. You're not going to have any problems unless you want to put in a new motherboard or something, and the more savvy people have actually done all kinds of wild things to their macs using l33t Hax0r skillz (i.e. voiding their warranties).

2. Macs are (and have been since the nineties) fully compatible with left-clicking and all those other buttons and wheels that a computer's mouse now has. Even that mouse on the newer Macs in your school's computer lab (the one with the funny looking "scroll ball"), which LOOKS like it only has one button is secretly hiding four buttons, and that funny looking ball actually lets you scroll left, right, and in some cases, in every direction.

3. Everyone knows Windows sucks, except for n00bs.

4. Now that Macs are all running UNIX, you don't NEED LINUX unless you just want it for it's open-source abilities and you don't like to have software. Also, I find it highly amusing that a LINUX nerd calls Mac Users faggy. Dork.
