I'm still using my 2008 15" Unibody MacBook Pro. Physically it's fine (other than a dent from a strap break on a laptop case a few years ago), but since upgrading to Mavericks a year ago, it's been almost unusable. Simple things like websites rendering in Safari take minutes, switching apps grinds the system to a halt, and launching programs like iTunes can go up to a full 2 minutes. It's still stock 2GB and with a standard HD. Will maxing the RAM or going to a SSD bring the system to usable speeds, or is it just a lost cause and save-your-money-for-a-new-one situation? I don't want to spend money on it if the end result is still an unusable machine.
