The UX380N measures just 6 x 3.74 x 1.27 - 1.5 inches and weighs 1.2 pounds and has a built-in thumb keyboard (slide up the display panel to reveal it).
Unfortunately, the keyboard still has very little travel and tactile feedback, and you'll need long fingers to reach the middle keys easily. Like the older US models, the UX380N still has an AT&T (Cingular) EDGE wireless module with a popsicle antenna that swivels up from the back.
We'd hoped by now that the UX would have moved up to a 3G HSDPA AT&T module, or shifted to Sprint's EVDO network, as we've seen on some Vaio TX models. Though AT&T's EDGE network is excellent in terms of coverage area and strength, its 2.5G speeds feel very "last year"

Access the Sprint Mobile Broadband services to extend your wireless coverage beyond LAN access networks and hotspots. The VGN-TXN25N gives you the freedom to go farther, do more and stay connected.
