Have you considered a hardware defect? Even Ubuntu doesn't crash the whole time. Also you see usually at least some obvious reason in the logs if it's software related.

Regarding the "extremely broken stuff": I came here from another thread:

I couldn't help to post the above after also seeing what's described here. (Given all the down-votes maybe not the smartest idea, but I honestly couldn't help :-)).

The problems are in my opinion indeed extreme and by now the mess gets undeniable even to die-hard fans.

What makes me really scratch my head is why otherwise reasonable people don't vote with their wallet and still buy this things (even at a premium!).
