Useless.

There is always a market for any useless thing and most of the time new things seem to us useless because we don´t know how to use them. ;)

As a laptop or even am UMPC for daily use, no, but I could see the Noahpad being useful in very specific situations…Open air kiosks, ATMs or public terminals for example, where a limited number of “point and click” or “pan and scan” functions are needed but having the option of entering small amounts of text would be good.

A lot would depend on how durable the system is.
