I just run small prob everyday like aim ie mail itunes things like that. I already have 512mb of ram and it toke all the slots so if i do get a 512mb chip i will have to take 1 out so thats y i said around 1 gig. I would love more space too.
If your ram slots are filled now, Guessing 2-256 MB, adding 512 would give you 768 MB. You will have to use 512 in both slots to get 1 GB. Don't forget, you have to remove RAM first.
