Oh Tegra, is there anything you can't do? Not only are you at the heart of the Zune HD, you're also the rumored silicon foundation underpinning next generation smartbooks, media pads, MIDs, and even the Nintendo DS.

While no details have been provided, one could assume that a device with that kind of power will be doing more than just refreshing electronic ink on a single display slab, particularly with dual-display e-book readers now the norm.
