Give me 380USD phone which lasts for next 5-8 years, feels premium, is repairable, camera is decent, replaceable battery, OS is just Vanilla Android with atleast 5 years(more years of Software updates would be welcome) of Software Updates and when you can't provide it, make it hackable enough to install Custom ROMs.
I've always been of the feeling that I'm buying this lovely, well-designed piece of hardware, why would I want to cover it up in an ugly plastic case?
