Right now, in my iPad 2, I got polaris office and docs to go. I used them for my presentation via projector. It was flawless until I need to show some equations terms which I made on MS-Powerpoint 2010 equation editor. On polaris office, the equation boxes turned into white empty boxes and in docs to go, it showed up as "not supported" boxes. Anybody knew if there is an app which supports equation editor ?. Or, I'm afraid I'm going to get myself another android tablet. Thanks to macrumors.com users.
