So, I have a dinosaur. Powerbook G4 (Ti-book) 667 mhz, 512 mb RAM. I finally after YEARS upgraded my OS (10.4.10), yay me! Just bought Adobe CS3 (for the new IMAC we have yet to buy), but I would like to install it on my Powerbook. SO, it it time to bump up to 1GB RAM. I was told it was tricky, and I should take it in to the apple store to install, but then I took a look under the keyboard, and it looks pretty simple. i have installed new RAM on a G5 tower, and this looks way easier. So, I am planning on buying the RAM either online or at FRY's, then installing it. BUT, I know I have to be careful of what type of RAM to buy. Any suggestions on brand or specifics? I found what I think will be good at http://www.ifixit.com/Apple-Parts/PC133-512-MB-RAM-Chip/IF111-013 but I will have to buy 2 (512's) as mine currently has 2 (256). I guess I just want to make sure I am not going about this the wrong way before I drop about $200 for RAM upgrade... Any other advice for my dinosaur?
