The Japanese blog, Macotakara recently brought to our attention NoteBookCase for iPad 2, a new case that converts an iPad into a mini laptop. The case features a Lithium-polymer auxiliary battery in the body to extend intervals between charges, a full size bluetooth-enabled keyboard, USB port, and mini USB port.

Available from Japanese retailer Rakuten and Amazon for 5,980 yen (or approximately $75), the description specifies that the case is not compatible with the new iPad, but we think with the minimal size difference of the iPad 3, might mean it’s compatible, too.
