What's this mystery e-reader? It's the Kobo Vox, and it just made its debut on the FCC's site. Is it a reworked version of the relatively recently released Touch Edition? Is it a brand new reader from the company? The device is listed as being an "eReader Tablet," so perhaps it's something more akin to Barnes & Noble's Nook Color or the Kindle tablet reportedly in the works from Amazon. And will Kobo's recent appearance at f8 play into the equation? It's hard to say, but there are a few things worth noting here. First, if the above rough image is to be believed, the device is touchscreen, as with the company's current product. The design, however, looks a lot more like the latest version of the Nook than the new Kobo. A side shot reveals what appears to be a microUSB slot (no shocker there) and a headphone jack, something missing on both the latest Kobo and Nook (though both the latest Kindle and the Nook Color rock one), while a "multimedia headset" was used in the testing. Also listed among the testing materials is a microSD card, so there seems a pretty good chance that this thing has expandable memory -- again, not a surprise, nor is the fact that the reader is listed as being WiFi-enabled.
