We got a nice helping of slides dropped on our virtual doorstep this evening, fleshing out Dell’s upcoming netbook — which they seem to be calling the “Dell E.” Um, Eeenteresting name choice, but that doesn’t seem set in stone, and there’s plenty else going on here to ponder over. Dell’s breaking the Dell E into two device types, a 8.9-inch model clearly meant to take on the Eee 900, and the 12.1-inch “E Slim” which actually looks positioned to take on the MacBook Air and X300, at a mere 0.8-inches thick, though perhaps in a lower-end capacity. Even the 8.9-inch model will have some distinctions, with E Classic model for super low-end use, and E Video and E Video+ for more RAM, larger flash storage, webcams and Bluetooth in the + model. Rollout looks to be slated for August for the E, August / September-ish for the E Slim, and a followup for both of those in October of WWAN, with WiMAX after that
