The presentation explains in detail why Android is not what most people refer to when they say Linux. What most people mean when they say Linux is the GNU/Linux system with it's standard userspace tools, not only the kernel.
The presentation shows how Google has simply thrown 5-10 years of Linux userspace evolution into the trashcan and re-implemented it partially for no reason. Things like hard-coded device lists/permissions in object code rather than config files, the lack of support for hot-plugging devices (udev), the lack of kernel headers. A libc that throws away System V IPC that every unix/Linux software developer takes for granted. The lack of complete POSIX threads. I could continue this list, but hey, you should read those slides. now!
Just one more practical example: You cannot even plug a USB drive to an android system, since /dev/sd* is not an expected device name in their hardcoded hotplug management.
