There has already been a vastly simpler system that predates OS X: Linux or BSD combined with X11 and an arbitrary window manager. Just stay away from anything that calls itself a "desktop environment" and you should be fine.
Some light at the end of the tunnel: Russia decided to scrap the whole system this year! I hope they will stick with that absolutely brilliant decision.
Let me rephrase what I really feel: After my three previous Nokia phones, I don't feel Nokia is a viable producer of high quality phones. In fact, part of me wants to punish them for selling me such junk and enveloping me in some sort of cognitive dissonance field that made me think they were doing good work.
Then again, Elop got there to change exactly that, so perhaps I should give them a benefit of doubt now.
Is anyone doing high quality non-smart phones anymore? I'm looking for something that's small, sturdy with long battery life. Preferably with good music playing.
I suppose Sony Ericssons's non-android phones are pretty good in that space, are there any others?
It's frightening how cars' software is bloating up. I would've thought that a product that very easily kills people if things go wrong would have been under more scrutiny.
Personal recommendation: http://www.archlinux.org & http://awesome.naquadah.org/ -- a nice compromise between easy configurability and the "suckless" simplicity mentality.
