“The problem which PDAs will still face, even once they follow this trend and become cheaper and more simple, is that people are not going to want to carry multiple devices with them. Despite what the Z22 has to offer, many consumer will opt to use another product, despite it being a good deal more complex, so that they will not be weighed done with electronics. The last bastion of PDA users may become those people who do not own a high-end phone or carry a laptop with them for work.”
