I wish every mobile browser manufacturer did this.
Well platform browsers kinda-sorta have this... if you install their SDK and run the bundled emulator/simulator (which may or may not be a pain, and may or may not be possible at all depending on your development platform).
Opera Mobile: come for the speed, stay for the HTML5.
Because most of the "tech media browser wars" is about desktop browsers? I mean you could ask the exact same question about Safari, nobody cares about it on the desktop, but on mobile…

Although their reported userbase comes from both.
The chain of efficiency is basically: Mini > Mobile with Turbo > Mobile.
Unless they merge the Mini's mode into Mobile, you might still want to use both.
