When using a non-mobile website, like Android Central, it would automatically fit the page perfectly when using the pinch to zoom feature. Can't get X to do that. Also, what's with the font? Know what I'm talking about?
I'm sorry, you specifically said pinch to zoom. No, Dolphin Browser does not reformat the area when you pinch to zoom. Only when you double tap, which doesn't help you at all.
If you were to use Dolphin, it would prompt you when you fire it up if you want to make it the default browser. I use it because I like the tabbed browser functionality it provides.
