Sun is evil. Need proof? Read this interview. Basically, Sun says that Linux is worthless as a server and that you should (quelle surprise!) run Solaris instead. Oh, sure, they're willing to use Linux-originated technology like GNOME, Evolution, and so on, but God forbid you actually run this stuff on Linux! You should instead give your hard-earned money to Sun, who needs it far worse than you do.

Sun will take the work and sweat of thousands of open-source programmers (almost all of whom were using Linux to develop the software in question), incorporate it into a slightly-modded "Java Desktop" (little of which is actually written in Java, by the way), and sell it at a profit without acknowledging the people who enabled them to get there. This is an amazingly uncool thing to do.

Now that Bill Joy has left Sun, any remaining geek-cred they used to have is now gone.
