AT&T / HTC Mondrian Ad Showcases Windows Phone 7
According to the ad, it will be a Windows Phone 7 handset and will launch on AT&T. No surprise there considering that it has been confirmed that WP7 will be a GSM-only platform (meaning no launches on Verizon Wireless and Sprint) until next year. In America, that leaves just T-Mobile USA and AT&T to launch these phones. It's hard to say how many people will flock to WP7 on AT&T; most smartphone users there seem to gravitate towards the iPhone or any number of BlackBerry phones.

The Mondrian itself looks like a capable phone, and the ad shows off WP7's ability to auto-update panels on the fly with information that users care about. WP7 definitely has a tough road ahead; it's designed to be used in portrait mode alone, and it will not support tethering at launch. Also, it won't have the marketing support of Sprint and Verizon. Have a look below for another peek into the world of WP7. Will you be making the switch this holiday season? Or does WP7 still not offer a compelling reason for you to leave Android, iOS, webOS or BlackBerry OS?
