I was asked in a PM about which game controllers were out there for iPad. But as I haven't posted more than 6 times I can't give this link to Gamesharq in any other way than going public.
As a result, I am adding the link here. It is a private page, so any views are obviously my own and should be taken with a pinch of salt. But hopefully some of it will prove useful to both the guy who asked and any others looking for info on controllers.
Just discovered I cant even add a link yet
you guys will have to work it out.
