I guess only time will tell how much hoop jumping is required to keep these things operational. It's certainly a good start. It has been galling to have to pay for the privilege of dealing with Microsoft's detritus - hacking and dumbing things down for the lowest of common denominators.

Anyway, thanks to Microsoft for finally doing something decent that should have done years ago. 

As a veteran of the browser wars I'm not sure if I'll ever get over my deep and visceral loathing of Microsoft and IE, but this is a baby step towards rapprochement. :-)
