What about IR/RF?

What a tablet like this needs and everyone keeps forgetting is an IR and/or RF transceiver instead of 3G, in my opinion these devices are not mobile enough to take with you everywhere but could really flourish as a multifunctional device for the "home".

These devices are great for universal remote control possibilities, especially with Maemo (linux) installed. I admit that it is possible to do this via wifi, but that's too laborious and/or slow?
