TechSpot published a review on the HTC Titan Windows Phone
The Titan is HTC's latest range-topping Windows Phone 7 handset. It certainly lives up to its name, being titanic in size and sporting a huge 4.7-inch display. Couple this with a 1.5GHz processor, an 8 megapixel camera, and the latest version of Windows Phone (7.5 "Mango") and you've got yourself a recipe for one heck of a handset.HTC Titan Review: Windows Phone 7.5 on a Giant Screen
Not only is the Titan's display the largest that HTC has put on a phone, but it's also the largest display you'll find on any Windows Phone 7 handset. It's not all good news though, as this obviously affects the overall size of the phone, and the display, though large, doesn't seem to offer enough pixel resolution. Still, with its narrow form factor and tricked-out camera, the overall package is certainly worth a look.
