Well, I have finally scraped together enough money for a new 12" iBook and some extras (I already have an extra gig of RAM). My biggest problem is that because I will be playing WoW and other games, I really want a faster hard drive than the 4200 rpm that it ships with, but I don't want to void the warranty (just call me paranoid). After doing a little searching in the forums, I've found several people saying an Apple certified tech can install the new HD for me without voiding the warranty on any other part of the iBook, but I went to an Apple store, and the "genius" said that they couldn't install anything they don't sell. Unfortunately, this same "genius" refused to believe me when I told him 7200 rpm laptop drives existed, thus ruining his credibility in my eyes. The "nonexistent" Hitachi 7k60 I'm looking at is here. http://www.hitachigst.com/portal/site/en/menuitem.c8c3966a526cfb5deb4703e3aac4f0a0/ Can I get a definite answer about the warranty, hopefully from someone that has had an iBook hard drive replaced?
