The projector would be really nice for setting up impromptu conferences. I actually used to use the TV out on my Touch Pro for doing slide shows and stuff on the conference room projectors.
This built in projector would be handy for stuff like that. Easy to setup and show a slideshow. What I really think would be nice is for our sales fleet. I can see our salesforce using these things like crazy to help concrete a sale or use it in their sales pitch.
I think I will toss this over to our Telephony group and see if we can get these on contract
