Ham sandwich, anyone?

David Needle has written an interesting article about the business use of next-gen handsets, within which there's a quote about how using a PDA to make a phone call is like speaking while holding a ham sandwich to your head. I couldn't agree more and see this as the main stumbling block towards creating the ultimate mobile business device. We're closer than ever to striking the right balance between form factor and functionality but we're not there yet (and progress is slow). When the ham sandwich becomes a chocolate biscuit, I'll be at the front of the queue.
