As a independent software developer that does a fair amount of web based work, I wished they had included Opera (Presto based Opera) in their compatibility list[1]. Yes, I'm aware most people don't use Opera before someone reminds me, but there are a lot of Opera Mobile/Mini users. On a personal standpoint, I like to make sure the js/css I write degrades gracefully and supports Opera Desktop too (something that Google has had troubles with caring about in certain sites they maintain). They also don't mention how it works on older versions of browsers (specifically IE and if it works fine on IE 9 and 8). I generally don't care about anything before IE 8 anymore, but with jQuery dropping support for IE 8 in jQuery 2.0, I am wondering if Google followed suit. It says only the latest versions of browsers[2], which if taken literally, means IE 10 only and that's a very small subset of IE use as a whole (like 1-2%) [3]. Also don't see any mention for how it works with the non-Chrome (though still webkit) stock Android browser that most Android devices come with by default. I mean it could fall under Chrome, but it's not the same and not all features are supported by the non-Chrome stock browser (and varies by Android OS version). I'm guessing it's similar to mobile safari though[4].
