Summary: Chocking bad in performance. MP3 - Media Player stutters on and off. Just not up to standard. Slow in performance and underpowered. Battery charge is not sufficient. I had two of the items and none of them lasted longer than 3 months before a repair was needed. Just stay away from this PDA.
Pros: not many....
Cons: Heavy, underpowered, MP3 does not work correctly, all over performance is just too bad. Service of HTC is at minimum 6 weeks for a basic guaranty repair. Shiny surface is full of fingers.
Summary: I had two of the HTC 3600i. Both of them have been an total failure in regards to MP3 performance and over all performance. The MP3 payer skipped all the time and often did not work at all. This may be the poor performance of Mobile Windows 6. Previous Mobile Windows 2003 was much better on my HP Jordana.
Pros: Handy and light, good touch screen, GPS works fine and is reliable.
Cons: Poor performance, frequently hanging of the OS, very poor performance in regards to MP3 playback and Bluetooth, Finger Magnet housing that drives you mad, very poorly designed earphones, the left cable is far too short, the microphone - remote part is upside down mounted and totally wrongly designed.
