All the things it can do could be done with Flash. They will not notice much difference.
For a developer, it makes coding easier / cheaper.
Any commercial website which goes for a 'html5 aesthetic' to look modern is likely to be the equivalent of a site ten years ago with a Flash splash page. Sites have evolved away from design-for-designs-sake, as it usually annoys people.

Shame it's not actually supported on everything. Not sure why it doesn't work on my PC, and really can't be bothered to work it out.

or is it an experimental thing which may be included in the future?
If Microsoft don't support it, then it is pretty useless in commercial web design (though I guess gamers are going to be more willing to be told to use a different browser).

And it's not really part of HTML5 (although that's a term that's come to mean a lot more than just the actual HTML), it's a non-standard context you can request from a canvas element. But there is already a decent consensus about it... except from Microsoft.
