Really love my Ipad 3.. I've started to use it as a laptop replacement on short business trips (I travel all the time). One limitation which continues to pop-up is the ability to work with complex/large spreadsheets (6+MB in size) or powerpoints..Takes forever to load or I get an out of memory message..I close all my apps, reboot etc but no joy.. I have the following apps: Keynote Numbers Documents to Go Quick Office HD Polaris Office Office2HD Any thoughts/suggestions?? TIA..
