I'm using chromium at work and at home and for me it works perfectly
I am not a huge fan of extensions - just gmail checker and adblock - so for me it's cool.
Sometimes I miss the pdf plugin which doesn't run on linux - but it's not some huge problem (evince works like a charm
Why chromium - in my opinion it's much faster than firefox, and using one field (omnibox?) for search or page address is just a pleasure
