I'm using the n900 for two years. Sometimes I want to smash it to the wall because it's so slow, but the rest of it is perfect(of course only when the repos work, what isn't the case). I can do everything with it what I want to and I like that people still create apps for it, so I can do even more.

A possible alternative would be a smartphone from Jolla, but I will use my n900 for a few years before getting a new smartphone.
