I just upgraded the RAM in my Macbook. Yay! Twice as much :) And I also bought a 1T external hard drive for photo storage. The photo editing software I use (Aperture) allows storage anywhere without heavy file duplication, so I'm going to download my photos from now on directly into the Terabyte thing and then just fiddle in Aperture. I also copied all my this year's shots into Terabyte thing and erased them from Macbook. I'm hoping this, with the addition of 1G RAM will stop the grinding and creaking that had been going on if I asked Mac to do more than one thing at a time :)
