Slightly thinner, ally body with resistive multi-touch or capacitive with a c-tylus + slot, hdmi out, usb host mode, full slide out qwerty like n900 (love this keyboard), 1ghz cpu (overclockable to nearly 2) with decent gpu, 1gb dram, a better Internal design to maximise heat dissipation and allow a larger capacity battery. HD vid, 12mp carl zeiss optics with a better apeture range, at least f11, xenon flash, face/smile detection (n86 has it). Support for usa 3g, I dont care personally, but I'm sure a few yanks do. Support for every orientation as standard. Less bevel, more screen, 720i screen. And to top it off, intergrated laser (death star style) from around the camera lens.
