Just back from sam's where I looked at and used one for about half an
hour and confirmed no video ports of any kind, in or out, just usb, (5)
ethernet, firewire,(?) memory card slot, digital audio and analog audio out.

The sam's $1,300 unit has half a terrabyte hard drive, four gigs of ram
and the touch screen had no problems with anything I tried using
fingers, although the screen was not calibrated correctly which created
a few glitches.

It's tablet on vista premium and includes windows media center.

One surprising fact was that the (very thin and light) RF wireless
keyboard has excellent range... was able to take it far enough away to
the point I could barely see the start menu pop up (~60-70') and it
still had a good connection.

Had it had video out ports, I might be $1,300 poorer at the moment ;-)
