Seems that the opportunity to proudly raise two fingers at the open source community and regain market share has been squandered by MS.
After following a link in Kev's recent blog entry, and reading the comments of the people who've tried the latest version of IE (and these would be people who are happy to pay for the privalege), it seems clear that they've fallen well short of target.
...PNGS not properly supported, still.
....RSS seems to be tied to the OS - meaning people running old-win/non-win miss out?
...and much, much more.
I think that an unsuccessful IE release could truly put the nail in the coffin of this browser...I'm sure that could have been turned around had the dev team listened.
