Unfortunately I cannot offer a good look; the teardown photos posted on the FCC website are incomplete. They stopped before getting to the point of disassembling the screen and the front panel, but I did notice one interesting change.
The new Aura lacks the internal microSD card slot found on some of Kobo's other ereaders, which might make it a little less appealing to hack. But other than that it largely the same components as any other ereader: a battery, circuit board, microSD card slot, and an E-ink screen.
This ereader is expected to ship next week, with a retail of $149. It's equipped with 4GB Flash storage, a microSD card slot, Wifi, and runs Kobo's proprietary software on a 1GHz CPU.
