There has been an explosion of interest in the Treo smarphones.  I personally own a Treo 650.  I am able to email, blog, fax (send/receive), surf the internet, print, use bluetooth, listen to music, take pictures, and… well the list goes on an on.  I primarily use two websites to learn how to use these incredible little devices.  The price is becoming more affordable and with the Treo 700w becoming available the temptation becomes almost irresistible.
