Tether Tablet to Camera for viewing Pics

Has someone come out with a tablet that you can tether to your camera through the HDMI or USB ports so you can view your pics on-site with a much larger screen than the 3.5" one on the camera?

If so, who, what, where, Price, etc. Is it practical?

EyeFi /= CF Cards.

to the OP, I've seen several different option depending on the tablet you have, but all of the ones I've seen require a Wifi network, or at least ad hoc network.... there's one for Android phones / tablet that allows live shooting with a cable running from the tablet to the camera... no PC / Wifi required... it's more for Live-View shooting than for picture review though..

Thanks guys for the reply.
