From what I have seen it appears to be unintuitive to use, but I'm not ruling it out before I can get a closer look.
And I have a tendency to kill my watches, so mine are about $20-$40.
I'm a complete watch/gadget hound, but I'll pass on this first version.
With the horrific battery life currently on my Verizon 9630 (thanks for the lousy OS "upgrade" big red!), anything that drains it further would be bad news.
Now, if they made a version with a microphone built in so I could reply to messages with vlingo . . . then we'd be talking! (Never mind that you'd look like **** Tracy talking to his spy watch . . .)
