In case you haven't already head, the HTC Hero is now available from Sprint. The Hero is somewhat similar in design to the European Hero, but it now doesn't feature the large chin that the European version has, and also has a larger trackball surrounded by flush (but easy to press) buttons that were all right below the screen on the European version. The Hero also is much snappier than the European Hero, which was known for it's lag time, partly because of the HTC Sense UI. The Sense UI is also on this version of the Hero, but it seems that the software has been modified so the lag time is gone from the phone. The whole phone is great from my use. It has a gorgeous multi-touch screen, a great web browser, and the entire phone is very customizable and has a great feel to it. Every feature of it is great, including the multiple home screens that now come with it. The virtual keyboard is also great, and you can use it either in vertical or horizontal, or use a modified (like the Blackberry Pearl) keyboard or a number pad with T9 text input, also. And in case you were worried about breaking it, don't worry, because the built quality is some of the best I have ever used (er, felt), and it doesn't seem like a few drops w0uld hurt this phone. It is available from Sprint for $179 with a two-year contract.
