same 3.7" VGA LCD...
and a thumb keyboard. Built-in Bluetooth and Wifi. Even Mini SD.
However, I wouldn't touch it. I don't like that sliding layout for a couple reasons. First, w/ out actually holding it, it looks unbalanced. Might be awkward to type on. But most importantly, that screen is going to get mauled to death being stuck on the outside like that. You will be changing screen protectors every week or less.
I don't like it at all. But Sharp is probably just offering a new smart phone on a different OS/platform, and borrowing from their parts bin to make it more cheaply. Imho, it won't be a Zaurus threat.
**edit** (stupid phone distracted me) of course, I could always be wrong. They pulled the Zaurus out of the US, they could always drop the Zaurus-line totally in favor of something else. I mostly just hope that it won't be a threat
