Guys, the phone thing has already been beaten to death. Too many times. It's not just the cost of components, with voice capability you're switching markets (see if that 15$ will buy you an upgrade from an iPod Touch to an iPhone). The fact that the Touch, Archos and others exist prove there actually IS a market for non-voice (potentially with cell data) devices. It's a completely different question which market you want to be (not) in.
