Thinking of getting the new Verizon 7100 series model, but I'm unsure about the 7100 thumboard and usability. I searched but couldn't really find a thread where everyone who used it and a 'one letter one key' thumboard feel about it.

What are your opinions - does it force more hunt and peck? Does it slow you down? Do you tend to make more errors? WHat was the transition like?
