The IE team is part of Windows and it's clear that their priority is Windows 8 and not Web in general.
Also I really hope this isn't the gimped shell that they've used for past previews- makes it incredibly difficult to use for any period of time.
Rapid is relative- FireFox's schedule seems too eager for me. For the web to move forward we either need IE being an active participant helping push forward or to get out of the way.
In general I'm disappointed with the lack of enthusiasm MS is showing for down level OSes.
Chrome and Firefox do not have very much version fragmentation compared to IE. Much like the Android issue, you cannot use the latest and greatest features because a large portion of your users are still on old platforms.
There is really three options available to web developers: 1) Do nothing 2) Employ some new features and allow for graceful degradation 3) Use the latest features and/or force users to upgrade their browsers
Most developers go for option #2. Browser vendors who employ a faster release cycle help reduce the time-to-market for new features to go mainstream.
I will make it simple: Would you rather wait 5 years to stop using images for rounded corners (border-radius)? 1 year? 3 months?
executive: have our websites been optimised for Windows 8? Marketing rag X said it was awesome, social network, _insert random buzz word_
me: err, ummm, I tested it on the preview edition of IE10... so I guess it works.
