Two days ago I upgraded the hard drive in my MacBook from Apple's paltry default 80G to 250G. I bought a compliant hard drive from komplett.ie for €76 and followed Apple's straightforward instructions. Everything seems to be working well, so it looks like I got a great deal on my upgrade (as I did when I upgraded the RAM in my laptop). The natural order has been restored and my laptop has more space than my ipod :-D
