I bought a 15" MBP with the 500 Gb 5400 rpm drive last week. Loving it. I heard there were click/beep problems with the 7200 rpm drive and the SSD's were just too expensive. I expect the prices to drop over time. Is it technically possible to install an SSD in a MBP at a later date (and do a fresh install of course)? I doubt there are any different internals of the MBP, but I want to make sure.
