TrustedReviews have looked at the Asus U3 notebook
A quote from the article:
Asus U3 Hands-On Review
The Asus U3 is certainly quite an unusual product. It approaches the 13.3in form factor quite differently to other manufactures, removing the optical drive but adding discrete and integrated graphics along with eSATA and GPS. In this sense it's very feature rich, and caters for a whole raft of niches not normally found on other notebooks. Whether this proves winning formula we'll just have to wait and see, and naturally you can tell us your thoughts in the forums.
