I have never had a Mac before but would like to get one. I am looking for a cheap, would like to stay under between $150-400 range, laptop to watch DVDs, do some basic Office and surf the web - and all wirelessly. I need a lot of help, I have been reading but I need a lot of help. Which OS do I need? Is a G3 enough and if so what speed? What about wireless? Any cheapos with USB 2.0 and/or firewire? Any other questions or requirements I am forgetting? Thanks everyone.
