Finally,
I finally have my hands on one tonite. Got a loaner for my first customer to get familiar with it. My first impressions:
Finally a touch screen not so crowded that I hit the wrong button by mistake!!!!

A lot better sensitivity than previous models with a stylus to boot.

love the quad remote screen. Its like having four remotes in your hand at once. and you can switch to whichever remote you want.

As far as wifi compatable devices I have only found some security cameras so far that are wifi capable. D-link makes one. They are $300 a piece. Panasonic will be coming out with one shortly as well. Still searching for devices I can control with this device.
Im sure there are many out there. By the way if you want to tie in x-box or PS2 to this device you will need a wireless access point for each one if you have both or a hard wired switcher to inregrate internet gaming to a theater enviroment.
Just an update
Thanks
