HTC, the Taiwanese phone manufacturer that produces more Windows Mobile devices than anyone else, launched three phones for the first quarter today at the 3GSM.

Well, actually it's hard to call these devices phones at all.

HTC Advantage

The one that stands out is the HTC Advantage (X7500), which fits nicely in the emerging category called Ultra-Mobile PCs, or UMPCs. The niche focuses on taking advantage of the ever-growing number of wireless broadband networks being built. It's bigger than a phone, but much smaller than a laptop. In addition, the battery is rated to last up to eight hours.

The device would come with the usual suspects, Outlook, Excel and Word, but it also has a couple of key features, including HTC's VueFLO technology, which uses "G-Sensor," a technology that allows users to simply tilt the device to move around the page.

Specs include a 3-megapixel camera and a second VGA camera for video telephony; connectivity options including HSPDA, Tri-band 3G, Wi-Fi, stereo Bluetooth and GPS.

The other devices mirror phones and PDAs seen today.

The HTC S710 will be one of the first to launch with Microsoft Windows Mobile 6, also unveiled at 3GSM.
