Smartphone As Your Computer

Sorry to be on such a smartphone kick, but I am trying to get used to my new phone quickly.  As most of you know you can edit your Google Docs items from any mobile device.  My students who have tried it get a kick out of working on their phone (and I've lost count of how many have done it on days their Internet have gone down at home or who just plain like doing it) and seeing the changes simultaneously on their laptops.  So the video above shows a person actually working on a GDocs item from their smartphone.  I found this video on Google Operating System and ones like this that allow you use the smartphone as the guts of the computer when docked in a screen/re-charging device.  But what gets me excited is this product from Ubuntu which connects your smartphone to a screen or this one which is essentially an empty laptop for which the smartphone serves as the guts. It is one way that soon schools will be able to provide cheaper access to the Internet for their students (not to mention already inexpensive devices such as the Chromebook).  In other words a cloud based classroom for all our students is getting very close (since schools will hopefully be able to provide laptops to the students without smartphones).   Here is the Android app for Google Docs and here is the iPhone one.
