Actually, there are limited places in the US that do this: Metric Road Signs in the US I think this is something that could be voted on at the municipality/state level and could eventually work its way nationally.

Mod the parent troll !

Chrome is very responsive, but come on, IE 7 is slow as hell ! Try to use about:blank as the start page, and you'll see that it takes around 2-3 seconds to start, with a message saying that it starts to connect ! Its Javascript engine is super slow, so using GMail is a PITA. As a developer, I have encountered nasty bugs in IE (like authentication problems, that need to reset the preferences !), so I don't trust this browser.

I didn't test IE8, since I never install MS betas anymore. Having tested a few of their hard-to-remove products was enough for me.

Anyway, I agree that Firefox gets worse and worse, not because of the memory isolation (who cares ?), but because it's slow to start. Anyway, the plugins definitely make it the best browser experience !

Chrome is very fast and nice, but if you wait for AdBlock, it's like waiting for TV channels to stop ads.

Frankly, you should stop using speed as a reason to use a browser. The main point now is TRUST. I trust in Firefox+AdBlock+NoScript more than any other browser.
