One thing I noticed is that there doesn't seem to be such a thing for mobile browsers yet. Maybe a worthwhile problem to solve? No good idea how to go about it, though. Would emulations be sufficient? Or maybe attach some real phones to a server and make screenshots (scaling?)?<p>I am not even sure how many mobile browsers there are. Would one have to test on every phone, or would major versions of webkit mobile, opera mobile etc. be sufficient?
I'm finding this really useful: in the past I've had to use a service that runs over VNC (crossbrowsertesting.com). Dealing with cross-browser bugs is annoying enough without additional slowness and inconvenience. This feels much, much nicer.
So, they made something that only runs on Windows. The one platform that runs all of these browsers natively anyway. Incredibly useful investment in time.
