New proud owner of a G4 12" iBOOK here! So far it's been perfect. Warcraft III runs like a charm. I'm deciding whether to add extra 512mb or 1gb stick of RAM on top of my default 256mb. Here's what I use my iBOOK for (or will use): 1. Multiple tabbed browsing - Firefox 2. Dreamweaver MX, Flash MX and Fireworks MX 3. Photoshop (sometimes) 4. i-Tunes & iChat always in the background 5. Warcraft 3 (sometimes) Correct me if I'm wrong - But will more RAM put less workload on my HD (therefore keeping it cooler)? I'd like to keep this laptop for at least 3 years w/o any problems. 512mb = ~$100 / 1gb = ~$225 Does anyone feel the difference between adding a 512mb or 1gb of extra RAM? I don't want to spend the extra $100 for 1gb if my system never needs a reason to use it. I know everyone recommends more RAM! But can anyone testify to difference I would feel with (a total of) 768 or 1,256mb? Also, internet page processing feels kind of slow/jerky sometimes. Will more RAM make a difference? Thanks for all the help!
