Its a terribly nice disease that is slowly infiltrating the PC world, and hopefully the Mac side of things will follow suit. For comparison purposes, my SZ650n weighs less then 4lbs and has a 13.3'' screen. The X505ZP (small one) is about 1lb and has a 10'' screen. I got it at a real bargain price a while ago and I really never used it, but I've got it back up and running now (it needed SP2 to run office 07) and its still a treat to use. Compared to my 3lb, 12'' Thinkpad X60. And finally, the model shot. If Apple released a computer that looked like this, I'd happily plop the 4k sticker price of this bad boy down.
