I have a first generation MBP which I just love. It's in great condition and has served me well--except for the 100GB hard drive. I am considering getting it updated to a 500GB 5400 or 7200 drive (if the Seagate Momentus is in stock at Best Buy) The hitch is that I can't really do this myself and was planning to take into an Apple authorized repair center and have them replace the drive. $400 includes cloning, labor, and the drive itself all done with 24-48 hours. (If I buy my own drive its only $160--which would bring the total to about $310) No lost screws, no blue screens and the upgrade is guaranteed. I'm looking at it as a stop gap measure until I buy a new MBP in 6-12 months but I'm not sure the cost is worth it.
