Intel might not support Microsoft's Windows Phone 7 but Windows could scale down normal windows or start from scratch on the core like its doing with Menlo(NT core but low power req with Silverlight UI) which could demand that high performance. Microsoft could bring out another type of device - something like the now canceled Courier which would be ideal for the next gen of Atoms(2011). However, the major type of question Intel should be asking is what type of portable and mobile applications will demand high performance? The only thing I can see happening is games & or video(but video is already adequately handled by majority of todays chipsets). Intel can demand an OS which in turn demands high performance but do the consumers want it? People are just discovering really good mobile needs.
Another player though could be HP which could demand the processor for its next generation of slates which will run on WebOS which also has a Linux OS running in the background. I believe that would suit Intels and HPs plan to really distinguish their products. A Moorestown based WebOS platform would be something truly unique in the marketplace. HP has already said that they dont see using Win7 in their tablets because its too power hungry, WebOS is another thing altogether.
Main question IMO is is Meego part of the (package) if you want to get off the ground running or will porting other OS be equally easy?

What do they mean? That Windows Mobile 7 isn't bloated enough to require such a fast processor. That the software is optimized enough to provide adequate performance with "slower" processors. I'm glad that operating systems do not "need" faster processors. Lets keep the requirements down, dont let the devs get lazy.

Why they have a chance, iPhone is good, and Android is getting popular, why phone maker want to pay for the OS?
