So my AppleCare finally ended on my iBook. I took it in to see a Genius because the battery has been crapping out lately. While I'll be getting a new battery, the Genius suggested I could upgrade my HDD. My question to you all is have any of you upgraded your HDD without professional installation and how did that go about? Where would you recommend getting a pro installation at an affordable rate (specifically in the Orange County area)?? What about hard drive recommendations?
