As I see it, wireless connection is the digital equivalent of Swiss cheese. I equipped my laptop with a software wireless modem. That includes the ability to update the site with clients' material as they watch. However, my office is in a hole in which no service is provided.
Many prospective customers have similar problems.
So my wireless capability is relegated to emergency backup only. Until the software is vastly improved, I think a lot of businesses will be reluctant to make the switch. I have no doubt there will be significant technical advancement in voice recognition in the time period you suggest. But to me, those advances appear to be the tip of the iceberg. We'll stand by our predictions, although we, too, have had problems using speech recognition software and wireless Web devices.
