In Windows 8, Microsoft's new Metro web browser is not going to support any plug-ins, most notably Adobe Flash. When Apple left flash off of the iPhone and later the iPad, there was great hue and cry. And, sure, Android runs flash on web sites but not very well. This sounds like the end of the road is fast approaching for flash.
Here's Dean Hachamovitch, who leads Internet Explorer development at Microsoft,explaining:
Running Metro style IE plug-in free improves battery life as well as security, reliability, and privacy for consumers. Plug-ins were important early on in the web’s history. But the web has come a long way since then with HTML5. Providing compatibility with legacy plug-in technologies would detract from, rather than improve, the consumer experience of browsing in the Metro style UI.
