Finding it very strange that this change is presented under the guise of safety, as there are absolutely very malicious extensions currently circulating on the Chrome Web Store.
They do seem to have very little policing of the Chrome Web Store. It's actually annoying to have an app on there that is legit, as so many of the top places in the store are taken up by unscrupulous rip-offs of Super Mario Bros and Sonic the Hedgehog. I could make some money too by putting classic games into a javascript emulator, plastering the page with ads, and submitting a few hundred apps (one for each game) to the Chrome Web Store. I'd rather play by the rules and have Google properly run their marketplace, though.
Depending upon configuration, it competes with the upper range 767/777/787s. http://i.minus.com/ibue0fziZTMd11.jpg shows the comparisons pretty well, as far as size alone is concerned.
