Personally I couldn't give two shits about _any_ browser getting "new and exciting!!!!" features right at the moment, and my reason is very simple,
They all fail at what they are supposed to do, first and foremost. Some fail utterly, and other fail a little bit, but they all _fail_.
There is not a single browser available for download at the moment that _fully_ supports the web standards laid down by the W3C, http://w3.org/ and developers who are working on Safari, Konqueror, Mozilla Firefox and Seamonkey, IE, Opera, Camino, and so on, all need to take a step back from their computers and say,
"Hey, how come we're adding new features to a program that isn't even standards-compliant?"
The continual lack of support for even the full subset of CSS 1 and 2.1 makes designing pages based on XHTML and CSS a frickin' pain in the arse.
If there was one browser, even just one, that was cross-platform and fully supported even just HTML, XHTML, CSS 1 and 2.1 (maybe even parts of 3), and was extensible to support such things as SVG and XVRML, then I would be using it in a damn shot, and then I'd _know_ that when a page failed to render properly, _I_ screwed up, not a bug in the browser.
Stop adding features guys, just follow the damn standards.
