Hi all. So. I'm getting a MacBook. Yep, I finally saved up enough. One of the two lower-end white models. Not sure which one though. I am so glad they just upgraded them all to 1GB of memory. It was shocking that they could get away with selling 512MB at that price. Now, I have a few questions... 1. So I'm looking at the two lower-end models. I see the difference is quite large for $300. One thing that strikes me is a 160MHz speed difference. Does anyone notice any difference between the two speeds? 2. How does the MacBook perform on 3D-demanding applications? Games especially. Not modern 3D shooters, but things like World of Warcraft. I've heard some rumours that its absolutely appalling. 3. I'll probably need to get a USB modem. What are your experiences with these? 4. How useful is the AppleCare Protection Plan? I'm in Australia, and $419 for the thing seems a little too much for extra two years. Thanks for your replies.
