Whether or not Android is a Linux distribution, it will still bring attention to the Linux operating system. Very few people in the mainstream understand that there is a difference between the Linux kernel and a Linux distribution. Android will be a Linux “flavor” whether it wants to be or not.
When Android was only able to run on mobile phones, this was not too big of a deal. People are used to having different apps for the iPhone than there are for the Blackberry. Not being able to use an app designed for a LiMo based phone on an Android based phone is not an issue.
However, now that Android is being ported to Netbooks, the fact that it does not natively support applications designed for Linux may be a bit confusing at first. Fortunately, the operating system is completely open source. There are already suggestions for the creation of an Android application that allows for the use of a sandboxed Linux environment in order to run native Linux applications.
