I've got the Desire until sometime in 2012, but I'm not an early adopter anyway. For a wish list though..
* Camera with any number of pixels, but a larger, good quality CCD please!
* Lots more internal memory and/or ALL Android apps supporting SD installs.
* Faster CPU, half decent GPU, full Flash, OpenGL and DirectX support.
* 4", high quality capacitive screen. Owt bigger and it'll be a tablet and not pocket sized enough for me.
* Full voice commands for the major phone features.
* Better browsers. Dolphin isn't bad, but it's not there yet.
* Vastly improved battery life!
* Dual sim card support would be nice. Business and private.
* SDXC or whatever the latest and greatest is.
* A more advanced marketplace. Google really need to work on it.
Not that I'm greedy or anything, but that'll do for now
