My guess is that an existing (already on the market) wireless remote pillow speaker would be better for the sound.
As for tilting the picture, this would be an excellent idea to suggest to TV manufacturers who could simply redesign the display circuitry to rotate the picture electronically (and silently). This would be an inexpensive remotely controllable addition to any digital TV display circuit. The picture would be smaller when rotated but would still be easily viewable if the screen size was large enough. This would be a nice option for anyone who likes to watch TV in bed (like me).
I will now spend 1 hour trying to suggest this (free) on the Magnavox website. That's all the time I have left but I think well worth it. They have been the most innovative TV manufacturer in the last 15 years -- especially with their "Smart Sound" (automatically turns volume down on those loud commercials) and "Smart Picture" (automatically adjusts color and brightness for type of program) that many others are now copying. If they don't go for it, probably nobody else will.
I also submitted it to all the others on this neat site I found while doing this:http://www.suggestionbox.com
