I have one in my collection somewhere; I even tried to use it a couple of times as a daily driver, but sadly, the project was just too alpha at the time for that.
Certainly interesting that Sun was trying to use it (as relatively open hardware, from a hacker-friendly OSS project, it's was well suited to a skunkworks like that) for their JavaFX work, but it certainly wasn't their own "JavaFX Mobile smartphone".
Some day I'll dig these devices out and have a look at them. Strange to realise how far we've come, yet what could have been much, much better if only CL and OpenMoko had the balls to follow through...
