I know it's really hard to open a MBA, but is it possible to upgrade the CPU if one were to venture into this? I currently have a Intel Core 2 Duo 1.4ghz, I'd really like to upgrade it to a faster Core 2 Duo (I obviously know it has to be same socket and what not.) I would even pay someone who knows how to do this, if they can guarantee me they can do it without any damage to the shell of the MBA and ensure the MBA will work. Let me know guys, thank you in advance!!!
