Minor nitpick: the keyboard toggle button looks more like a calculator and does nothing for the 'Auto' option (maybe it should be hidden until one of the other layouts is selected?)
Firefox 17 (Nightly as of now) web developper tools includes a Responsive Design View.
Chrome Web Tools too probably.
Nice bookmarklet nonetheless
This doesn't work correctly - on my iPad, rotating my site to landscape from portrait just makes everything slightly larger, rather than triggering a different layout, as this does.
Other tablets may not behave the same way.

or iPads...
Otherwise it is indeed an interesting concept.
Is the keyboard toggle working correctly? It seems to push everything up instead of sliding over it.
Well executed. Needs solid testing though. Scrolling on larger pages doesn't seem to work for me.
