Just to pass along, a couple of stories today indicating that Apple's started to test some of the components likely to appear in the next generation of iPads. Expectations are that the iPad3 will feature a higher-resolution screen, with wider viewing angle and better visibility in sunlight, and a new processing chip. With testing just beginning, the pundits don't expect the iPad3 to be available for public sale before the second quarter of 2012.
