I think the keynote left me with a lot more questions than it did answers. How well do Metro-ified apps work in a multi-monitor setup (do they really all have to live on one screen?), what's to stop malware running whatever that magic command line that defines the 'refresh' setup?, does WinRT completely replace Win32 or is it all going to be a bit WinForms-esque?

And a list of Enterprise questions as long as my arm (and a bit more) but hopefully now the silence is lifted we'll start to see more of that story unfold too.
