Like Amazon, Opera wants to build a more efficient web browser for Android than what is offered by Google. According to CNET, they're calling it Opera with Turbo. Inelegant as the name may sound, the idea behind it is anything but.
Here's a comparison I ran using the new data-tallying feature of Opera Mobile and Opera Mini. The BBC's home page is 1.7MB, a size you can check using Opera running its default state with Turbo turned off. Turning Turbo on shrinks the page size to 519KB. With Opera Mini, the page size shrinks even more, to just 304KB.
Not only does this allow for quicker page load times, but will also cut down on battery consumption since your cellular radio won't be frying itself trying to load a massive page through a weak signal. Amazon's Silk browser also revolves a similar concept, rendering parts of webpages and caching them on its own server, in an effort to improve speed, user experience and ostensibly, battery life.
Opera hasn't said exactly when the Opera with Turbo browser will become available for Android devices except that it will be here in "early 2012". [CNET]
