Kinda off topic, but Opera Mini and Opera Mobile for Android is vastly superior in terms of smoothness compare to all other available browsers. It is very noticeable especially if the page is heavy. A good test is to load this page http://www.html5rocks.com/en/tutorials/internals/howbrowsers... on your Android in different browser and test the responsiveness.
I use Opera Mobile exclusively on Android. Pages load faster and zooming with fit text to screen works really well.
My one frustration is that when launching a web page from another app it always opens a new tab so I end up with 10 tabs open and have to close them all every so often.
I've been using Opera Mobile for a while now. IMO it does tabs best for tablet browsing - however I've had to switch to Maxthon as Opera was just too unstable on my android device.
