I'm not sure what you are talking about when you say it's not easier.. it's 10 times easier. It's nicer for development too. Less waste of time and unnecessary code just to make your web app appear and work the same across browser. It's really a joy to develop for unlike for desktop.
It's also 10 times easier to JUST STICK TO THE FRICKEN STANDARD, and don't use the damn prefixes. less resources, better code, faster site, cleaner code. and far less effort.
Just because you're incapable of coding without adding in 50 fancy and completely unnecessary "cool" effects that are only supported on some browsers, doesn't make it harder, it just means you're unable to to not add in lots of unnecessary CSS code that makes your life harder.
Also you're not supposed to code for browser, you're supposed to use the standard function for checking what is supported in the browser visiting the site an activate CSS effects based on that. easy, and clean on the code and efficient. as opposed to checking for the browser and manually adding code for each browser and each version of the browser.
Also as for VRML2... err I mean, WebGL.... bwahaha. sorry that crap isn't and shouldn't be used, EVER. it makes horribly designed 100% flash sites look like user friendly interface masterpieces. and it's horrible to use for games as well. better to use an actual plugin for that, r an actual app. but hey you're completely against separate apps like flash and think html5 is the greatest best thing ever... err wait a min now...
