The Shifted Librarian has a post about these cool new flat products. I actually saw a commercial for the phone and radio the other day. Pretty keen. They need a way for the battery to last a real long time so you could use this technology for other things. I'd love to have one that was kind of a remote control that I could stick onto a coffee table, just for the basic stuff like changing channels and volume.
Of course the speakerphone is fun too. Imagine someone's reaction the first time they hear the phone ring and you reach over to the wall and hit answer on the phone and start talking. Of course even the poster radio is good for stuff like that (even if it does probably sound horrible).
