Actually...
Come to think of it...
Brings back real great and ugly memories...simultaneously ...
You mentioned Mer ..Kabouik....
Now it is just a layer ...
Good for marketing...
Once though...
Long long time ago...
It was something different....
It was an open alternative to maemo ..
Running on the n800 and n810...
Before the team back then decided that they could not go any further with it (mainly due to the closed bits that Nokia could not release ...)
Anddddd...
Left it to pursue other endeavors ..
But they did do a pretty fantastic job with what they could.
I still use the old Mer...
Love it ...
(Well hell...I love running Diablo turbo, KDE, Debian, Windowmaker, and E ...not to mention all the others ....on my n8x0's....)

Great and sad at the same time ...it is...
Outdated options are still fun ones to use and explore....
And is still better than having zero options...
