I think a fairer test would be: -Nokia N9 (PR 1.3) -iPhone 4 (iOS 5.1) -Samsung Galaxy S (AOKP build40) Then compare battery life, overall speed and functions. Then comparison of accessories and physical hardware. And I mean the international SGS model, as the EPIC 4G (i9000) will run rings around them all with its qwertyboard, gamegripper and native Ubuntu.
