lonny: Like GadgetLover said, more RAM is DEFINITELY advisable. You seem to have only 256 megs. OS X runs much better if you have more. I would suggest maxing out your PowerBook, if possible. RAM, even notebook RAM, is considerably cheap these days.
When I bought that first 256 meg chip to boost my comp to 448 megs of RAM, OS X ran much better. So when I saw that an online retailer was selling 512 sticks for under $50, you know that I sprang for the opportunity -- and now I have 896 megs (64 meg stick had to be removed
).
As a side note, I would definitely recommend
www.boundlesstech.com for memory. They had EXCELLENT customer service (by this, I mean that when I ordered the wrong RAM for my dad's old G3 powerbook, I left a message with them, and the guy called me
3 minutes later and told me he would waive the restocking free and send me the correct RAM of the same amount for no extra charge), excellent prices, and so far it seems, excellent quality.
