I'm not aloud to have one because we really need to conserve memory! Only my dad is aloud to change it. We have 5 people who use this computer and I know I have like 250 pictures. That's a lot for one person! I really need to get a job and get my own computer! I think I'll buy a used mac on ebay. I've had pretty good luck w/ ebay so far, I got a nice saddle!
