Totally forgot about this thread. I'm writing this from a CR-48, so I'll give a little synopsis of my impressions so far.
First and foremost, Google did indeed deliver on the speed aspect of this machine. I've clocked it a couple of times at sub-10 second boot times, and 10 seems to be the norm. Browsing is also quick, and the wireless connection I'm running on has seen consistent high speed, so no drop-off there.
Physically, the machine reminds me a lot of a early black Macbook, but ever so slightly heavier, although not so much that it's a problem. The keyboard has been changed to play into the function of the OS, as the Caps Lock key has been replaced with a search key, with pulls up a search menu quickly, making searching in general a breeze on this machine. The Control and ALT buttons have grown, and all of the keys are textured, which was pretty nice. The display is 12.1 inches, and runs by default at 1280x800, although it's not a super nice display. The trackpad is over-sized, and is pretty snappy, although not quite Macbook snappy. There are a number of multi-touch functions built in, which all seem to work pretty well.
Outside of the keyboard, the box has a single VGA port, a USB 2.0 port, and SD card reader, (which I haven't really bothered with to date), and a headphone jack. No optical drives at this point, but we knew that going in. My only disappointment in this department is in the fact that you can hook up a monitor to the VGA port, but may only run one screen at a time, that is, no dual monitor display.
Overall, it's a very nice machine, and speed seems to be the main feature, which it's more than delivered on. I'd personally like to see some changes made to the display itself, and am pretty excited for the potential addition of optical drives, but overall, a very nice showing by Google.
