Very cool! I've had one for a couple months... I just got my notification application running. It allows me to be notified when an inbound call is coming to one of my video conferencing rooms..
Also, there wasn't a basic "large character" clock, so I wrote one on the flight this morning.
With it set in Airplane mode (and then turn on wifi) I'm able to get more than one day of battery life... which is pretty good...
My next step is to build some "service/sticky" apps to run in the back ground...
Well worth the $150 I paid for it.
