PDAs used to sell rather well in the days of the Palmpilot and Psion. Windows CE devices, a bit less so.
Of course what we were all using them for were functions supplied by any half decent smart phone these days. Basic calendaring functions, note taking, documents, e-mail, games, and the ability to create vertical applications. The alternative was a bulky filofax or a huge laptop.
Once phones functionality started increasing, it was obvious the days of PDAs were numbered.
Another ten years and you'll probably be laughed at for having a desktop. You'll either slot your 'phone' into a dock, or more likely it'll all be wireless. All that will be on a desk will be a monitor, keyboard, and mouse because a decent form factor does matter. Everything will travel with you, in addition to being stored online.
