The XV6800 has the newest design HTC keyboard (which is very good), integrated 802.11 b/g WiFi, integrated Bluetooth 2.0, EV-DO, 2 megapixel camera, and more. In comparison to the AT&T Tilt (see my first impressions), this device does not have an integrated GPS receiver. The online specs also state it only has 64 MB RAM, which can be quite limiting on a Professional device and I hope this is just a typo for a new product page.
It is available online now at their online store. The press release states it is priced at US$449.99 after a US$50 mail-in rebate and new two-year agreement, but the online store shows it as US$399.99 after a US$100 online discount with an additional US$50 mail-in rebate saving you more.
