At present they're ridiculously priced -> Almost as expensive as a 20" iMac. And two thirds of the price of a 27" computer iMac.
An elegant solution could be to re-introduce a (cheaper) 24" Cinema display?!
Would it be possible to separate the antenna's from the actual phone?:
One could carry a little receiver (containing all the antenna's) in your pocket or backpack. The little device could send the voice/internet/text message to the phone?!
