Because I'm such a doting partner, my relationship with my Macbook Pro 1,1 from March 2006 is still going strong 6+ years later. She still looks & runs like she's brand new. Unfortunately, her tiny 80GB hard drive was just packed to the brim with photos and music, but I wasn't ready to let her go for one of those less aesthetically-pleasing black keyboard models. Thanks to iFixit, we've been given another year or two on our relationship with only about 45 minutes of effort! Couldn't be happier.
Simple simple simple. The detailed step-by-step photo-inclusive directions on iFixit were perfect and seamlessly guided me through the process. 45 minutes later, my Macbook had 500GB of love to give instead of the original 80GB, and we'll have another year or two together!
Definitely weigh the options when considering doing tech work on your devices. After reviewing the steps & watching the video, I felt that I could execute this particular repair, but there are others that I wouldn't try just knowing my skill level at these things. Do your research before jumping in!
