This thing is incredible! It's a 4G 20 GB model. I'm a little worried about dropping or scratching it, but other than that this thing is almost perfect. I haven't had a purchase from Apple since waaaaay back with my iMac DV. I'm really keen for a G5 or a PowerBook now. My sister is expecting her iBook any day now, with an iPod Mini to follow. That's my 2nd switcher so far.
