I'm getting anxious. I've heard some nasty rumors about bugs in the early machines. However, the one I've seen in person looked great, and seemed to run really well. Unfortunately, the warranty on my Powerbook expires tomorrow, so that will probably affect the resale value when I get around to selling it.
The good news is RAM for the unit is getting cheaper all the time. I found 1GB sticks for $99 a piece, with free 2-day shipping from ZipZoomFly.
The sooner I get this thing the better.
