I suppose it is considerably better with a 1.4ghz cpu than my 1ghz cpu and the dual core helps with gaming, yes but im talking about general speed of the phone, in and around menu's, apps and settings. My biggest gripe with my galaxy S is that access to the phone or caller menu is that its to slow to respond(the most important part of the phone) same applies for taking a picture....more often than not, ive lost my oppurtunity because im waiting for this thing to load. The GSII for eg, is lightning !
