As expected, Apple has sent out invitations to select members of the media inviting them to a special event on March 7. The image accompanying the invitation features a finger reaching out to touch the Calendar icon on a noticeably high-resolution iPad screen, and the tagline “We have something you really have to see. And touch”. Notably, no Home button is seen on the device, although it may simply be rotated to the side. Apple is expected to unveil the third-geneartion iPad at the event; the device is expected to feature a Retina Display with four times the pixels, as well as 4G LTE connectivity and a new chipset, all in an almost unnoticeably thicker shell that we first saw at this year’s Consumer Electronics Show. The event will be held at the Yerba Buena Center for the Arts Theater in San Francisco and will start at 10:00 a.m. Pacific Time.
