I dumped my SureType unit because it was driving me nuts. It seemed to confuse the silliest words (it would type "tea" instead of "yes", "hey" instead of "get", etc).
In my opinion, the x100 models (8100, 7100) are for prosumers, and the x700 models are for power users who really want an effective messaging tool.
