The Nokia n900 was SO ahead of its time https://www.youtube.com/watch?v=o2LL6nVzTp8

Linux based smartphone! That felt great! Fold out keyboard! With GTK! Based on Debian!

I've still NEVER used a phone that felt as good as the n900 did

@cwebber The N9 that came after the N900 was also incredible (no physical keyboard though). Such a missed opportunity.
@fabrice @cwebber I had also the N9 and really liked it. There was also keyboard version aimed at developers, the N950 (https://en.m.wikipedia.org/wiki/Nokia_N950). Shame Nokia didn't put more resources for the maemo/meego platforms.

@korkeala @fabrice @cwebber Wow, nostalgia...

[I was employed to work on the stack for the N9 (ofono and telepathy and a few other things) shortly before nokia gave up. I didn't develop anything for the N900, but used one A LOT for testing maemo stuff.]
