Thinking of Thinkpads, etc.

The IBM-Lenovo stories remind me of my ongoing search for an ultra-ultralight laptop. Will anyone ever break the two-pound barrier with a 12" screen so I can live with my laptop in hand (or in purse/briefcase)? The Thinkpad X40 and Panasonic's Toughbook W2 both reportedly weigh in at about 2.7 lbs. But the Thinkpad doesn't have a touchpad, so that's out for me. Now if the Toughbook would just forego its built-in optical drive and beef up its max. RAM to a gigabyte or so, shedding a pound in the process . . . .
