If YOU were in charge of the next "Surface" device

Microsoft has arguably created some pretty high end hardware in their Surface tablets. They have hinted at other hardware that they will be releasing as well, under the Surface line. The Surface is akin to Google's Nexus devices, the halo product that show the hardware vision, as a platform for the software to really shine on.

If you were in Microsoft and in charge of the next hardware device they were making, what would it be? Don't limit yourself to tablets (ala Surface name), what hardware would you like to see made by Microsoft as their next halo product, and what specs would you give it? A phone, a laptop? I'd love to hear all your opinions
