I'll start off by saying that the Sony VAIO UX Series is not for everyone. But for those who are fans of PC handhelds like the OQO, the Flybook and the Libretto---- the UX Series, in my opinion, is the pick of the crop.

I was plagued by back pain two weeks ago, and the Sony UX180P couldn't have come at a better time. The beauty of the UX is that you can hold it over your head like a Sidekick 3, or on your stomach like a Sony PSP. The screen is  super bright, and I actually used it as a flashlight during one point at night. It comes loaded with a full blown version of Windows XP Professional. The OQO has the Tablet Edition, which I can't seem to understand why anyone would use a 4 inch screen as a tablet.

The UX features a QWERTY keyboard that you expose when sliding up the screen, similar to a T-Mobile Sidekick. The keyboard, unfortunately, is also one of my pet peeves. It doesn't have the bumpy feel of a handheld keyboard. You actually have to use your nails to type effectively. Ultimately, my tasks were limited to short emails, IMing and web surfing. Longer writeups were extremely frustrating.

Web surfing is ideal because it comes with both WiFi and CIngular's WWAN technology. You basically have an internet connection no matter where you are.
