Is the document editor actually part of the base Android install, or is it in the mess of programs that the phone manufactures (like HTC and Moto) add to Android or the programs that the carriers add to Android?
If it's one of those, it's great you get a document editor out of the deal, but because that type of arrangement is precisely why it takes a long time for most Android devices to ever get a new version of Android, if they're ever updated at all.
