It's still unusable on Linux, but I like where it's going.

i try to use it as my second browser (just to see whether it could be the first one). and the only thing that keeps me off - not all extensions are supported _at full fledge_. e.g. surfingkeys (for vim-mode) which i've been using pre-dominantly for many-many years in FF. apart from that i love the experience. it's a great browser and i'm looking forward for it to keep up with the counterparts.
