I was just wondering if it is possible to upgrade my hard drive in my ibook g4. I just have the standard 30 gig drive, and I'm regretting not upgrading before I bought it since now I have my ipod which is 40gig and I'd like to store my music on the hard drive. Is it possible to say take my ibook to an apple retail store and have them upgrade it? if you can, any idea on how much it would be? i know it was only 75 dollars to upgrade to 60 gig if you did it before purchasing, but I'm sure it's gonna be a lot more since I already purchased. I looked on the apple store and all they had were external hard drives and i'd prefer not to do that unless i absolutely have to. Thanks so much for any information!
