Like all previous years, this year probably isn't any different, and it won't be the break out year for Linux on the Desktop.

But...  (there's always a but).

Something interesting happened over the last year.  People I never expected to be Linux users have installed Ubuntu.  My sister in law and nephew both count in this list.  At some level "regular folks" have now come to Linux.  I have no idea if this is a trend or not, but I find it interesting regardless.
