I agree with Jason as well. I will stick wih the LP and the mini until they stop working, all while looking for replacements.
I have TOS and I am slowly losing the use of my pinky and ring finger. I had to change from a "normal" keyboard to something else a few years ago and found the LP and when it looked like I had to type one handed for a while, I got a mini and a FrogPad. The latter looks funny and would be easy to use if I had a useable pinky and ring finger but I don't and so it wasn't whereas the mini was slow but it was doable. It was well worth the expense even knowing that Fingerworks was dead.
I must be one of the few people trying to type on the Fingerworks keyboards with 6, sometimes 7 or 8 useable fingers and I don't think I have to tell anybody here about what happens when finger 9 and 10 drop onto the keyboard all of a sudden
But it does allow me to type and work which I couldn't do anymore using other keyboards. I will also use this until either the keyboard or my hands give up.
Like other people have said: a big Thank you to all of you who are looking at alternatives and are posting here about their finds.
