No, I am interested in any electronic approach plate display usage.
There is of course a huge step-up in cost from somebody displaying the free national plates on say an e-book reader or the ipad, and somebody displaying Jepps on an MFD where you have to pay £2000/year for the European VFR and IFR coverage.
I am sure a lot of people have the latter capability (at least retrofittable into anything with a G1000 or similar) but I bet few are willing to pay the going rate.
