Having gathered quite a bit of attention on non-sped technology blogs, such as Engadget and Sci-Fi Tech, I thought it might be time for me to mention Tango! from Blink Twice.
The Tango is a handheld, dynamic display device with unique picture symbols (although you can import anything you want) and a built in camera for taking new photos to use as symbols. The symbols are arranged into talk topics for easy access (although you can program anything you want).
The Tango has spelling/typing options with word prediction and can be used as an adapted keyboard for documents, e-mails and more.
It runs on Windows CE, has about 8 hours battery life, built in scanning and switch ports. It only weights 2.5 pounds and has dimensions of 12.5" x 4.4" x 1.8. It is water resistant and has a tough wear resistant design. It also looks cool and was designed by some of the same people who made the X-box.
It costs about $7000.00 (gasp) and is distributed by Ablenet. The price would be its most obvious downfall. Others I can foresee without trying it out are non-standard symbols and a limited symbol set, not-yet-distributed desktop editing system and a maximum of six buttons per page,
