Have a look at Sony's new wireless appliance. This is a Japanese site so unless you are fluent in Japanese you will have to settle for just looking at the pictures.
I'll be adding a new folder to my picture pages with some external and internal shots.
The link between base station and the hand held unit is 802.11b. The base station has a 56K modem (sorry no broadband connection), TV antenna connection, and audio/video RCA jacks. The display unit takes a memory stick and has a 800 x 600 TFT touch screen display along with external keyboard and headphone jack.
You can watch TV or a DVD while surfing the net and sending email from any place in your house without any wires. You can set it up for your own ISP too (Phone #, DNS,POP3,STMP can all be changed).
