The best smart phone on the market as of April 2010 is the HTC HD2 on T-Mobile! This amazing piece of hardware has a huge 4.3 inch screen that uses capacitive touch! It supports 480 x 800 resolution! The phone is blazing fast with a 1 GHz Snapdragon processor. It runs Windows Mobile 6.5 flawlessly and has the HTC touchflow home screen. It comes with a 5-megapixel camera, a 16Gig microSD flash card, 3.5mm headset jack. This phone blurs the lines between CellPhone and Netbook. I picked up 2 of these beauties for $200. That is $100 a phone with a 2 year agreement.

 The reviews on Amazon say it all:  5.0 out of 5 stars
