Does it have to be a straight line antenna? I've seen tons of little FM radios out there that are built into head phones, MP3 players, etc. So, I wonder if you can make the antenna wind around in a circle or square or something.
A better mediaplayer with more formats (mplayer with more arm optimizations would be nice.) It should play the new mpeg4-stuff(h264 and aac) at full speed.
15) And, a pair that combine #13 and #14 would be nice (bluetooth device that is both stereo headphones and a phone headset).
4) Segregated internal memory
19) flash via wifi+web
