Hey everybody I'm interested in getting a solid state disk for my UMB 2.4. I have mostly standard apps - skype, adium, iLife, office, etc. My question is: How much space will I need for various applications and, of course, OSX? I'd like to have at least 5-10GB available for saving files and downloads when away from my external. Should I be safe and go with the 60GB or will a 30GB drive be enough?
