The best feature is the different ways to text message.  There is a querty keyboard and you can also write incursive on the touch screen (neatly) to get your message transcribed.  I also liked the idea of reading someone's whole memory card at once to determine what I wanted bluetoothed to me, instead of one song at a time!  Everything on their memory card shows up on your screen all at once.  It has computer programs like Microsoft Word, Excel, etc.  You can type a word document and save it to your computer or vice versa.
