I have been using the Chrome Beta for about a week now. I really like it. The UI is very smooth and integrated, and the browser itself loads webpages lightning fast for me. I would like to see more options in the settings, like Download options and the like.
I read somewhere that Google plans to make Chrome the stock browser on its pure Android devices. Can't remember where I read it, but that is the rumor. So it is likely that features from the stock browser will be implemented into Chrome eventually.
