I have Jeppview and Flightstar in fact the full suite with all the update services and more than happy to demo. I can also give you a demo disk of them that will run for 30days.
I actually get all my updates from the internet for the services rather than the CD's. It is easier and cheaper.
You can also install the software on upto 3 PC's which works fine for me. I have one on my desktop and 2 laptops. I personallu have had no problem with the copy protection but then I have found no need to pirate the software! It is easy to move the licence key from machine to machine so if you chance PC's you just deactivate the one instance and reactive on another machine.
I run the Flightdeck on a tablet PC, but to be honest prefer a printed plate and the overlay in the GNS430's. My view being that if I cant read the plate and fly the approach then perhaps I should not be there in the first place!
