Here's one last next-generation iPad rumor to mull over before Apple's official announcement tomorrow. Ex-Apple developer Jamie Ryan published a blog post (via Gizmodo UK) claiming Apple is working on an iPad 5 case that "mimics Microsoft's touch cover." The new cover would be an improvement over Apple's current Bluetooth keyboard, and allow the company to "differentiate the larger iPad" from the iPad mini, according to Ryan.
"Apple already sells a Bluetooth keyboard that functions perfectly with the iPad but it’s not quite as integrated as Microsofts offering, requiring a lot more bag space. This is the primary motivation behind the development, as all of the current solutions are fairly inelegant. Apple realises the market for the large iPad is mainly professionals looking to work on it whereas the iPad mini is mainly content consumption.
