We're not sure how we missed this, but it seems the Nokia N900 (aka "Rover") was not only mentioned, but visually detailed in some candor during an Nseries presentation way back in October of last year. If you fast forward to about the three-minute mark in this video, Nokia's next-gen, Maemo 5-powered internet tablet is seen doing its thing, and it differs in a few key details from the last leak -- most noticeably, it's got a big d-pad on the left just like its predecessor and there's no sign of an earpiece for making calls over the rumored 3G radio. In fact, it really just looks like a whited-out N810, which makes us wonder whether this isn't purely conceptual, especially considering the age of the video. Either way, the N810's aging rapidly and the territory's rapidly being encroached on by MIDs of all shapes and sizes, so we imagine we'll see this get launched soon enough -- maybe on T-Mobile USA of all carriers, if the rumors pan out. Follow the break for the full video.

Update: We're being told that this was little more than a student-led art project -- and it's one hell of an art project, considering that it looks every bit as slick as Nokia's official marketing. Thanks, Ryan A.!
