So after a few years of wanting to own a Mac, I got my hands on an iBook G4 in good condition. Here's the specs: 1.33 GHz 512MB RAM 40GB HDD Combo Drive Leopard OS X 10.5.6 I've been reading up on Mac stuff for a while, so I already knew that Leopard would be a bit sluggish on this iBook... and there is noticeable lag frequently, so I'm looking into getting a 1GB RAM upgrade for it. Any recommendations for what brand to get/where I should buy from? I've been looking at NewEgg and TigerDirect so far, kinda pricey. My other question is, after being a PC user for over a decade, what exactly can this Mac do that's really head-and-shoulders better than a PC? (besides a lack of viruses! ) Thanks for any suggestions.
