A friend of mine has one of these and I got to play around with it on his home wireless network. I like it. It intergrated into the network with no prob. Screen size and quality are good and it fits right in your shirt pocket. You can use a stylus or the wheel mouse. I was surfing the net and downloading stuff to his pc hdd in no time. All sony did was take a laptop and shrink it down to palm size. I give it a thumbs up and this will be the next hot gadget to give this christmas. If of course you don't mind coughing up 700 bucks for the thing.
