The SlateBook runs Android 4.3 Jelly Bean. (An HP rep told me that an upgrade to Android 4.4 KitKat would be provided "in the next couple of months.") Besides the usual suite of Google apps (e.g. Chrome, Drive, Gmail, Google Maps, Google Play, YouTube, etc.), several popular third-party apps are also pre-installed, including Box, Evernote, Hulu Plus, and Skype. HP provides its own branded apps: One for printing to HP printers, a file manager, a media player, and cloud services for online printing and file storage. None of this software can be uninstalled.
