If you are currently using Ubuntu 8, the upgrade to Ubuntu 9 will involve the implementation of Ext4. Ext4 is a super duper very fast file system that will make your computer sing. Sing fast.
If you are not using Linux at all, say you are using WinDoze, switching to Ubuntu 9.04 will make your computer run Two Zillion times faster, and it will not keep breaking and doing annoying things.
But remember, Linux is NOT FOR EVERYBODY. No …
It is only for cool and smart people. For everybody else, Windows. Because Microsoft is there to help you.
