When people say Linux, they usually mean more than just the kernel. Stallman insists we call this GNU/Linux since a good portion of userspace comes for the GNU project. When people say 'real linux' I believe they are referring to the full userspace that usually accompanies the Linux kernel. The userspace in Android is very different from the userspace in GNU/Linux. In GNU/Linux, it is very easy to program using your preferred programming language. This isn't the case in Android, everything is very tightly wrapped up around Dalvik. Before you mention the NDK, let me say that it's only a subset of C++ (no exceptions among other things). Ubuntu on the cell phone also opens up the possibility of things like shell scripting, local webservers, etc. What this really comes down to is programming freedom that you can find in GNU/Linux that isn't found in Android. You will now have a full fledged computer in your pocket instead of a limited device.
