Almost my dream smart phone,
Slim, Light, a very nice sized high res screen.
Short battery life : if you are browsing internet, checking emails regularly or playing games, the battery runs out very quickly.
Gravity Sensor : with some applications it does not work, you are stuck in portrait mode.
Connectivity : Great, I can use WIFI, connect to my home wireless, or Wireless hotspots, almost a laptop like control and feel to connectivity features. GPRS, BlueTooth, GPS is standard, however the installed GPS application (Google Maps) is not very good, but there are many good free GPS apps available on internet.
Internet Browsing: Opera Mini does not play Flash videos, I installed skyfire and it works a treat.
Crashes : It happened twice in the first week, when i put the device to sleep, it could not wake up, had to take the battery out and put it back in again to recover. I think this fault is down to Windows Mobile OS rather than the handset.
I cleared storage and restarted, it has been working ok now. hopefully HTC will release a windows 6.5 image when it is released.
Email's functionality is great : supports internet and exchange setup.
Navigation, Buttons and Themes: HTC's Touch Flow gives same experience as experience than iPhone, however there not many applications available for Windows Mobile. If Touch flo is enabled it hides windows theme.
If your previous handset had a key pad, On screen touch features will take a little time getting used to, but iphone users will find it very familiar.
Techies can tweak things further by changing underlying windows mobile features.
Overall a very good smart phone, One star deducted for Crashes but I can overlook that because rest of the features work great.
