I do. Only Nokia (I'm a Finn, after all!). Right now I am up to 17 working specimens. About 15 have hit the trash thanks to faults and malfunctions. My collection dates from 1993 to 2004.
It's a GREAT hobby!
Altough some people tend to think I'm wierd when I speak into my old, beloved
Nokia 2110 in the middle of Helsinki's hypermodern cameraphones!
