Microsoft has built a Windows Phone 7 simulator in HTML5. It lets you get a feel for it on iPhones and Android phones.
I tried it out, and yes, it would be better if the iOS chrome went away to give you the full experience, but it’s still pretty cool.
I don’t find myself saying this often, but Microsoft did a nice job with WP7.

Jonathan Zitttrain for Havard Law School:

The PC is dead. Rising numbers of mobile, lightweight, cloud-centric devices don’t merely represent a change in form factor. Rather, we’re seeing an unprecedented shift of power from end users and software developers on the one hand, to operating system vendors on the other–and even those who keep their PCs are being swept along. This is a little for the better, and much for the worse.

Hey mister bigtime Harvard guy, being a bit hyperbolic with our title, aren’t we? It’s link bait and I bit, big deal.
I love how the article is just a recap of every step Apple has made in the last 5 years.
And the truck metaphor is more accurate.
