I have two TouchStream keyboards (one for work, one for home) that are about a year old and working fine. With the company's demise, I am just wondering how long I could reasonably expect to be able to use those before having to switch to another ergo solution.

Does the lack of moving parts mean this will work forever, or do the touch-sensitive materials have a life-span?

And when would the lack of driver updates be a show-stopper? Will I be out of luck when I upgrade to a post-XP Windows version? Or will I be ok as long as I have access to a 2k/XP computer to run the configuration utilities when needed, then just plug-and-play on the newer Windows OS?
Thanks!
