This is a truly remarkable device - a mouse and fully functional keyboard combined, that sits flat on my desk along with all my other papers and books (try that with a traditional keyboard and mouse - its not easy). The TouchStream takes up little space, is lightningly fast and accurate, and folds up to sit neatly next to my iMac when i don't use it. As with anything worth the effort, one needs to spend some time learning how to use it - one even does it with a car or a bicycle, and even a pen, so why not with a keyboard. I have the QWERTY version, but type Dvorak and have also activated the mouse on the left hand side of the device. I'ts endlessly configurable to suit just what you want. I have a TouchStream at home and now want another to use another at work - but FingerWorks are now not operating any more, so i'm hoping to get one second hand. It's beyond me why anyone would use a clunky keyboard and a separate erratic mouse (as most are) when something so remarkable is available, or rather, was available. Is there not some other manufacurer that wants to take up making these keyboards?

Purchased unit at the suggestion of CISCO sales rep after inquiry on home network set up and getting my CISCO wireless router to cover the whole house. Set up was a bit long and required paying CISCO a fee to get all my devices up and running [had a Wireless CISCO 310 that was outshide warranty period and had to pay a fee to get it set up on this router] Long story short - unit worked well when it worked but had frequent loss of connectivity and required re-set each time. Finally got on phone with CISCO tech support and tried to fix. Inexperienced tech on phone flashed unit, but was unable to get it to work again - two hours later on phone, he gave up and offerred replacement, via paid RMA to/from [$30+ ship to get it replaced] - no empathy on his error - just put me on hold for the next custoemr service rep to process RMA. His last comment was \"this is not the right unit for your house - you need to upgrade\" End of day - paid more than the original cost to set it up and return the bad unit back Just sharing ...
