Apologize if there is a thread on this. I did a search but didn't find anything. Anyone have any thoughts on the possibility of replacing the internals in a late 2010 model 15" unibody macbook pro with the internals from the new versions released? (Essentially replace to get the new sandy bridge equivalent of whatever you have) I know in the past with Apple, while the outsides tend to look the same after an update, the insides have changed and the screws align differently and such. Does anyone know if they did that this time? I can't really find anything that definitively says so or not. The only thing I know for sure that changed was the addition of the little thunderbolt logo to the casing. I have a 2.66mhz i7 15" macbook pro that I bought last october. I couldn't wait for the updates that were coming because I needed a laptop asap after my original one was stolen from my office while I was teaching a class. I like my laptop. It works fine, but I was just wondering.
