Why bother with browsers at all then? They might as well come out and say everyone should just ditch free web browsers and just install an Adobe plug-ins or a Silverlight runtime, buy their application servers and IDEs, and code in the language that they dictate instead of more open and continually developing web standards that the majority can agree on. That's what Adobe and MSFT hopes. They still think it's 1999 and they can take over your web experience and tell you what is "Rich Internet Experience" and what is not. The only 2 reason Flash continue to be used are 1) annoying ads, and 2) porn. I still haven't met anyone who thinks an entire site developed in Flash provides an enjoyable experience to users after about 2 minutes besides Flash developers and managers that hired them.
