The Loop has reported Apple is having a media event on 7 March, 2012.
From the image of the invitation, it looks like that the next iPad has no home button at all. It says
We have something you really have to see. And Touch.
Let’s see if there’s a 7 inch iPad 3 (no likely) and whether the home button is really gone on the next iPad. iPad 3 with Quad core A5X & A6 chip, 4G LTE, bla bla bla… keeps flooding the web these few days.
