Won't use as default until someone discovers how to change the User agent, which I'm sure won't take long. Maybe Chrome Browser + will be released by the guy who made the ICS + browser? However, I love the tab interface, and it has been running very smooth for me thus far. It is indeed faster than the stock browser. At first scrolling can bug and make everything on the screen disappear, but eventually it scrolls very smoothly and fast. is silky smooth and hasn't been jittery or freezing for me yet, and omnibar is fast to populate.
Definitely a huge improvement! Love it!
