WOW - go back to the Droid or Windows phone, you don't deserve to be an iPhone owner - seriously the screen is disgustingly good looking (go watch a HD video on YouTube) - text looks so great, the camera is much better, a flash, front facing camera, speed is there (especially when coming from a 3GS with OS4 installed) - I'm going to stop now, I'm sure Apple will let you return it if you actually hate it that much....
I think people are confused and expect the "experience" to be different, it's still an iPhone with the same OS you had yesterday, come on......
