The market is beginning to be flooded with ultra-mobile laptops. I myself plan to replace my reasonable powerful laptop (at least it was 2 years ago) with one extremely powerful desktop + one ultra mobile laptop. Dell E: http://www.engadget.com/2008/06/12/dell-e-and-e-slim-revealed-taking-on-eee-and-air-in-one-fell-sw/ MSI Wind: http://en.wikipedia.org/wiki/MSI_Wind_PC
It'll be hard to top the EEE imo, i've been highly impressed with my one. The wind looks a little too big for my likeing but the dell E looks very nice, very tempting .
