Microsoft is planning a fresh new Surface tablet that would constitute a departure from the 10-inch designs to date. The tablet, if it comes to fruition, is expected to have a 7.5-inch display, Rhoda Alexander, director, Tablet and Monitor Research at IHS iSuppli, told CNET. That jibes with NPD DisplaySearch data provided to CNET in May. Alexander says her information shows it’s an RT tablet with a 4:3 aspect ratio and a 1,400×1,050 resolution display. Another possible feature — though not confirmed by either IHS or DisplaySearch — could be 3G/4G capability. That would be a first for a Microsoft tablet. Michael Angiulo, corporate vice president at Microsoft, told CNET earlier this year that one of the key reasons for an ARM chip-based RT tablet is the ability to add mobile broadband.
