From a look at the tech specs on Apple.com, it appears the iPad 4 retains the same dimensions and weight as the iPad 3. But I haven't read any hands-on reports yet that can confirm or deny a change in display tech. iPad 3's inclusion of older tech in an LCD display caused uneven lighting and overheating issues. I want to know if this is fixed before I go buying iPad 4. IGZO's the type of display Apple wanted for the iPad 3 but it wasn't ready quite in time. Now it is, and the inclusion of IGZO to fix such obvious design flaws should be a "no-brainer."
