Veno, yes your right that Nuance doesn't do this. And there may be a reason why. But the truth lies in the fact that no matter what Onev does, nobody seems to be interested in buying the product. So it really doesn't do any good to try and compare these companies. It's like trying to compare Nuance to IBM. The bottom line is their in the same sector and Nuance is the leader by millions of miles.
In fact, Onev isn't in the game yet. There sorta like you when you were sitting on the bench trying to get in the game cheering on the sidelines.
And on top of that they were listening to your advise on how to improve the product. That alone is possibility one reason why it doesn't work that well.
