I think I will be purchasing the 17" MBP in the next week. The price that Apple wants for a SSD is outrageous, however to honest, I have no idea how expensive the solid state drives really are. At some point, I want to replace the 500GB drive with a 500GB SSD. How easy will it be for a novice like me to do it? I was able to replace a drive on my older 15" MBP but it was not SSD. Also, am I correct in assuming that because of the 300 SATA that the SSD will work better in the 17" than the 15"? Also, what are the prices of aftermarket SSD these days? Are they even in the 500GB capacity yet? Thanks as always!
