Hello guys, As a fresh owner of iPod 4g I am going to purchase some games. When I was browsing the appstore I came across same HD games for iPhone, that I can additionally run on iPad. The question is: can you actually feel the difference between SD and HD while playing on iPhone 4/ iPod 4g? Or maybe HD visuals can be experienced only on iPad? Sorry for my poor English, hope you guys can understand it^^ thx in advance.
