Chris Welch for The Verge:
Microsoft has just announced that it will permit Flash content to run by default in both Windows RT and Windows 8 beginning tomorrow, March 12th. Until now, compatibility in Internet Explorer 10 has been limited to a select number of sites whitelisted by Microsoft.
I was just thinking that I wish there was another reason never to use Internet Explorer 10. Wish granted.
Also, no mention of Silverlight — which says all you need to know about that.
