If you like the htc experience then yes you will love it. Now heres the kicker its just a stock sense 3.5 and it hasn't been out enough to be developed yet. So coming from a fully developed phone like the Tbolt, its hard but this phone is what an upgrade from the Tbolt should feel like. Just pretend your running a 3.5 Rom with very minimal amount of bugs, and faster transitions, and a way faster 4g connection. Also just to be clear the screen size is different. The Rezound is more narrow which pairs better with the 720 p resolution. Also everthing on screen is smaller because of the resolution. Andbjust to give you real life examples MAPS looks like it would on the IPhone extreme clearity, and beautiful resolution. The text is smaller, but more refined, no pixelation or lines. The phone fits better in the hand, and you can't tell a difference really that the screen is smaller. So is it worth it YES its an awesome device, and HTC just does it better than Motorola, and Samsung.
