I'm planning to soon pull the trigger on a base level 13" MBP with the intention of upgrading the hard drive (and possibly later the ram) myself. For my purposes (casual computing and light design work with little time constraints) I'm thinking that beefing up the hard drive of the base level MBP will give me the best bang for the buck on a budget. Can anyone offer advice on a good hard drive model to choose for the upgrade? Any thoughts on going @7200 versus SSD? I've been hearing tell of the current SSD technology not being ready for prime time, risking failure in the not too distant future. Thoughts? Thanks very much.
