Yep, I originally ordered my iBook with the standard 30GB drive as I thought I'll just buy a big 2.5" HD later on and change it myself.
But now I've already made up my mind that I'll get a PowerBook at some point so I'm not gonna do anything to this machine.
And at the same time I'm pissed that I didn't take the 60GB drive option Apple offered, this 30GB is so small. I do have a 200GB External FireWire Seagate Barracuda but I'd like to have a bigger internal drive as well. 🙁
