I've got it, I'm using it, and it was life saver. I would
like to pay for the xtra but the developer's site is in Korean and
I can't find the order button. Also, any advise on it's stability
out in the field would be appreciated, it seems to work well as
long as it doesn’t get interrupted, like closing the
projector while it’s uploading, in which case it crashes
rather than throw an error. Easily enough handled with an exit lock
but I’d like to know if there are any other surprises.
