I was looking at the ASUS and the Dell micros, and I am considering the HP 2140 micro.  It looks like it has the best bang for the buck, and is under two pounds with an 8.9" display.  It can be upgraded to a 10.1" display.  Base price is $279.  It sure beats this 15lb Dell brick I was issued for toting, although the brick is a CAD level machine.
