For many people your Android system comes with OfficeSuite Viewer 6 pre-installed and it's one of those things you can't uninstall unless you have root access.
So to that end why not just install the full OfficeSuite 6 Pro... mostly the cost would be the issue for something you may not need or even really want eating up your system resources.
But what if it was only $0.99 (NZD1.25) on a three days special ending 10th May?
OfficeSuite Pro 6 + (PDF & HD) can be moved to SD card. (Approx 4MB resident when on SD or approx 17.0MB on phone)
Still not able to integrate, uninstall or move the original pre-installed OfficeSuite Viewer 6 (16.4MB) to SD that came with the phone (two minutes of checking)... ...oh well.
Note to self - Get root access to phone. [yawn]
