What the hell is the point of forking over 300 bucks for a "SuperDrive?" Cant I just go on Newegg.com and buy any random DVD writer (if I even needed one) and swap out the CD drive for much less? 3. On a PC 512mb is NOT enough memory, is 512 enough for a Mac? I usually have 3 programs opened: AIM, IE (2 websites usually), and some word processor 4.
