Prizing OP for Mac and/or iPad

Hi, I’ve just purchased OF2, OO4 and OP3 all Edu Pro for Mac using the faculty discount. That basically means that for me now OP3 Pro for Mac costs the same as for the iPad, which I find a “little” overpriced with around 160 Euro. I understand that programming is different for OS X and iOS, but I’m basically buying the same software for two devices for the same prize twice? And there is of course no discount on iOS as that seems not possible with the store concept… I’m still struggling buying the iPad version. I think OmniGroup could sell the iPad version significantly cheaper as any “power user” will use and buy the Mac version anyway.
