I have the 2.4 GHz model with the original 2 GB RAM and, if I remember correctly, a 250 GB hard drive (whatever the standard issue was). It still runs pretty well with Snow Leopard, but I was considering buying a new MBP when the next line comes in and passing this one along to my son. What upgrades would you recommend, especially if we were to switch to Lion? I figure bumping the RAM to 4 GB is a given, but what about the hard drive? Size isn't as much of an issue as speed. Anything I could do to increase the speed? Anyone had luck with hybrid SSD hard drives? If they're reliable and actually increase the speed, I would be interested. I've read a few negative comments here and there, but would like to hear any comments/recommendations this forum has. Thanks!
