Oh computers!

I ordered some new memory for my PowerBook that came in the mail yesterday and I'm so scared to put it in my computer all by myself. I looks like it's pretty easy, but I'm still afraid of messing things up! I've never actually opened up my computer before.

After having my computer crash last week I lost everything. Luckily I had all of my files saved on an external hard drive, but all of my software is gone and I can't find the discs for any of them.

Does anyone where the best place to get MS Office (really all I need is Word and Excel) inexpensively for a Mac is? It sucks that we've already bought these programs. I think Steve must have thrown them out when we were packing to move not realizing how important they are.

I need to get a few other programs as well, but really Office is the one I REALLY need right now!
