The router frequent drops the WiFi signal. The manufacture's tech support has made several suggestions to address the problem - everything from switching the frequency bands, re-setting the router, to replacing it. I have done everything asked, including router replacement and it still drops the WiFi signal. At this point, I may have to dust off my old R6300 NetGear router (which never had these problems).

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?

I purchased this from Best Buy over a year ago. It has been a great, dependable machine. The only complaint that I would have is there needs to be documentation on how to replace the memory that is not in the expansion slot.
