The future, they say, is based on the Internet and mobile computing.

The Toshiba e740 Pocket PC is the third PDA from Toshiba released in the past year, and is targeted at the business user. This does not mean its a bland PDA, as it is the fastest on the market thanks to its 400MHz Intel Xscale processor.
