N9 was good but the rest were awful.

N8 - chunky, fiddly screws to replace battery, plastic ends that showed wear and then the horror that was the camera island.

E7 - take the N8 and add a bad keyboard. Make the camera worse and the battery worse.

X7 - make the screen bigger but still keep the crappy nHD resolution. Cut the corners off so it looked like something out of abad BBC SciFi series.

N900 - spongy screen, tiny battery, keyboard you can't type on, a pointy stick, lens protector which scratches the lens, badly attached USB port and make it about an inch thick.

IMHO you listed some of the worst Nokia designs.
