I'm rapidly losing interest in my iphone 4. I had a 3GS before this and I was hoping that 4 would bring an even slightly different user interface design, but no.
The menus haven't even changed colour since the very first iphone, in fact they're even still using the same ringtones and message tones. OK we recently got about ten more tones, but they all sound like freeware .wavs from 1992.
My eye is being drawn to Android every day. I did have a Nexus one in between these two, but I sold it on because I was disappointed with the app market (and also because the guy I bought it from was dishonest; he advertised it as new but it transpired that he had bought it second hand, and he even gave me a Samsung charger!), but that seems to have come on in leaps and bounds since last year.
Really the only thing that was keeping me apple was the apps, but now that android is huge and offers massive customisation options, well, apple are going to start lagging behind in my eyes.
OK so the next iphone will be bigger than the last one, but if it's exactly the same in all but size (and probably a faster processor) then I'm going to have to pass with a yawn.
