The official black and red flip case for the Dell Streak 7 first seen in April and just featured in a mobile bundle deal last week is now available for purchase for $39.99. It's still not part of the Streak 7's dedicated accessories page for some reason, but it can be chosen as an accessory with the purchase of the tablet.
The pop-up window details of the rotating case, as it's called, includes a handful of photos and a description of what it's all about. You'll find everything except a link to order it (since there's no way to buy it separately right now) below.
The case itself seems rather heavy duty, as the specs indicate it's 0.48 pounds. I'm not sure how I feel about adding half a pound to the device, but perhaps the functionality is worth the extra weight. The rotation is pretty intriguing.
The design on the interior red leather is similar to what's printed on the Streak 7's back, which is a nice touch.
