Creating the Windows 8 User Experience
Jensen Harris (via Brooke Crothers):
Even with multitasking in the existing desktop still present (and improved), we did feel like only offering “one-at-a-time” in the Metro style experience was a bit of a constraint, and not totally true to the Windows history of multitasking. So we evolved Snap for Windows 8.This feature lets you run any two WinRT-based apps side-by-side, so that you can watch a video while you browse the web, or video chat while checking mail. And we created facilities for background processing of a wide class of apps, and background notification capabilities that are unique to Windows as well.
I like how open Microsoft is about their thought processes. It’ll be interesting to see whether they can pull off this “no compromises” thing.
