I love the pinball arcade, but I do have one issue with it.. I have to re-buy if I want it on another system. I suppose this is no different from any other video game, but it would be nice if perhaps they cut you a break when you login (Oh, I see you purchased black knight for iphone. Well then, it will only cost you a dollar instead of $2 when you also purchase it for ps3).
I mean like I want to have it on my iphone, but sometimes it's nice to play it on my wife's ipad, so re-buy. Then it's on ps3, so I think "well, that's got even MORE resolution, and it's a big screen". Unless your a person who just doesn't have a console to play on, I can't imagine there being a big market for a PC version. Also I imagine once it's on the PC, it's probably going to get pirated (something you can't do on a console).
