The way I see it, the current direction that wireless technology is taking will eliminate the need for personal digital assistants, which include but are not limited to Palm handhelds, Handspring Visors, Windows CE Pocket PCs, and Britain’s own Psion range.
The mobile Web will pull a disappearing act, as well.
Lest you doubt that well-financed, well-hyped hardware can fail, how many companies bought into and still use those hybrid Windows CE mininotebooks?
They were called Jupiter devices at the time and ran Windows CE (created and backed by a fairly large software company). The devices themselves were made by such leading industry hardware giants as Compaq, Hewlett-Packard, and IBM.
Mobile phones will become the dominant way to access data because, when the smoke clears, no later than next year people will discover that the kind of data they want to access is easily displayed on a mobile phone.
Best case scenario? We will see a hybrid of the original smart phone. These will be smarter phones with enough capability to store a calendar perhaps, but with their major strength coming from access to short bursts of information, something that will be available to all mobile phone users.
The mobile or wireless Internet will also disappear, as IP (Internet Protocol) becomes the behind-the-scenes technology to deliver data that is either pushed or pulled to you. The only information sent down to mobile phones will be requested, through either a corporate script or a personal profile.
