haha i think i'm going to start using that word. But yeah i'm pretty sure that it should still work as long as its the same size, which i'm pretty sure it is.
Give it a try. I don't see what could go wrong with it. If there are problems, revert to the original setup. I doubt the data will become corrupt during transfer.
I moved my HDD from one MBP 13" to another MBP 13", both 2.26GHz version, and it didn't work too well. Took about 30 seconds sitting at the apple logo while booting. As for Windows, it freaked out and thought I wasn't use a "genuine" version of Windows. Ended up re-formatting.
