I already have a copy of MS Word to use, and am buying 10.2 on CDs for $10 shipped. I used 10.2.x for quite a while on my G4 PowerBook with little/no problems, I'm sure it will be fine for my mom. Also, it will have 320mb RAM. Right now it has 224: 1x 32, 1x64, 1x128. I had said swap out a 64mb for a 128, I forgot and meant 32 for 128. So it will be:
315mhz
320mb RAM
6mb Vid RAM
USB (I added a card)
10.2.8
