Sony's new wireless LCD TV

So the big deal about Sony's new wireless LCD TV which they just announced in Japan, the KLV-20WS2, is that it uses WiFi (either 802.11a or 802.11g) to wirelessly connect back to a base station where you plug in your DVD player, game console, and/or cable or satellite box so that you don't have to run any of those wires directly into the television.
Not sure if it has batteries or not (which would make it useful for dragging to different places around the house), but it's definitely a boon for anyone wants to wallmount their TV but doesn't want to deal with any cables (except for a power cable, of course) running up the wall. Sharp has had a couple of these out for months now.
