An anonymous reader writes "With Android 4.4 KitKat, Google's biggest blow to Microsoft isn't against Windows Phone. It's against Microsoft Office. You see, KitKat ships with Quickoffice, letting you edit Microsoft Office documents, spreadsheets, and presentations on the go, without paying a dime, straight out of the box. This tidbit was largely lost in the news yesterday, given the large number of improvements and new features that KitKat offers. Yet it's a very big deal: every Android user that upgrades to KitKat will get Google's Quickoffice, and every new Android device (starting with the Nexus 5) that ships with KitKat or higher will also get Quickoffice."
