Nokia...
N95 - Reboot problem, crashes intermittedly, especially running the Fifa Demo. Send for check, asked to come back, female technician say ok already. Recreated the crash less than one minute. Blasted her and her engineering degree - Don't think your customer don't know about your phone. Battery meter problems.
N95 8GB - Camera has dead pixel, all photos taken got this annying black clump of dots. After that slider tercabut!
5310 - Headset problem.
N73 - Joystick tercabut. And I was very carefull with it.
N85 - Battery got problem.
N86 8MP - This one is the hardiest Nokia I got. It survived my daughter, who is fast becoming me.

Have to sorok all the screwdriver already,
N70 - Ah, was it that long ago? Screen backlight stopped working.
Not to say I didn't have problems with others, but maybe I'm just picky also.
