The second-generation iPad hasn’t yet been announced. But already, rumored details of an “iPad 3″ have begun circulating. The speculation continues today, with Apple Insider reporting that the iPad 3 will be smaller than the current 9.7-inch iPad - and could even be considered a “larger iPod touch.” It will have a screen similar to the iPhone 4. According to the most recent prediction, the iPad 3 will have a screen with double the resolution of the current iPad.

It was originally rumored that the iPad 2 would get the Retina display upgrade. But subsequent reports indicated that the yet-to-be-confirmed second-generation device will come with a display that is thinner than the original iPad, but which has the same resolution. All that said, the iPad 3 might not actually be an “iPad” at all. Instead, rumors indicate that the device may be placed into the iPod line. As always, stay posted, because these types of rumors are subject to change at any moment.

We haven’t yet had a glimpse of the iPad 2, but rumors and Apple’s yearly upgrade cycle suggest that it is, indeed, in production and on track for a spring debut. One of the most glaring omissions from the original iPad was the lack of a camera. This will be rectified on the iPad 2 in a big way. It won’t get just one camera, it will get two of them. Also, the iPad 2 will be thinner than its predecessor and have a flat back. The current iPad has a rounded back, which makes it difficult to set it on a flat surface, like a table, and work without it rocking back and forth. The rounded design was one of the only problems critics noted with the original iPad, and Apple has been quick to fix the problem.

Stay tuned for it’s unveiling sometime in Spring 2011!
