I have one of these sitting next to me right now, and it's essentially unusable due to the dispaly lag, and largely (though not completely) reliant on a service from the vendor for syncing. The hardware is passable, but the software is not, and it seems to be at a very slow drip of maintenance, if not completely abandoned.
