You could connect to a TV, as well. Honestly, for actual IT/programming persons, such a set up is unlikely to be be exceptionally useful, but I could see using Ubuntu Linux on the phone in more modest ways. You could play a native Linux game (perhaps one you coded yourself), while using a Bluetooth controller. I'm kind of grasping for straws here, actually, but I'd say that the dex pad is pretty cool more broadly speaking. For example, you could use your phone's unlimited data to play back netflix or YouTube videos while connected to a TV. You could use the Samsung dex mode (which predates this Ubuntu mode by several years), while relying on only the touch screen to launch the playback of said video. For me this seems uniquely useful because my mobile carrier, T-mobile, limits tethering to several GBs (and bypassing it hasn't worked in the last few years) and it would be unwise to spend them quickly just to provide a data connection to the smart TV or another intermediary device.
