I choose safari every day. It uses less power and it's an overall smoother and better integrated experience. It's also not constantly hounding me to sign into Google accounts.

"Pushing the bounds of the web" specifically isn't a huge goal for me, I want to see the bounds of computing pushed. That doesn't have to be on the web. The web is Rube Golberg-esque enough as is. [edit] To be clear I'm not opposed to it, I'm neutral to it.
