I have always been a an of the PDA, known also as the Personal Digital Assistant.  I love that you can have a simple device like a phone be able to access email, keep a calender, and even work as a GPS if you are lost.  The most exciting technology in this specific area is right around the corner.  It is a PDA called the Blackberry Thunder, and it is the first PDA by blackberry with a full touch screen.  It has only four physical buttons, and no slide out keyboard, making it extremely sleek and stylish.  I can not wait to see what kind of phones this company has next.
