OpenSource OS's that Don't Suck?

Do they exist?

I liked Windows XP and Vista is a horriffic pile of fail but I don't have an actual XP CD. I don't really know anything about open source OS so I don't have a clue where to start.

Bonus if you can actually run programs on them instead of just have a machine sitting there you can't run applications on because it sucks. If I want that i'll use Vista.

I sure do love how my buggy POS Firefox software crashes about 1% of the time that Internet Explorer did.  Of course, IE is ALSO free.

I sure do love my Gnumeric, which hasn't crashed at all, and cost me fucking zippo.  (Thank you, Gnumeric guys.)

If Microsoft imploded tomorrow, we'd still get by.  After all, we have Linux, and any company can take the code and sell copies all it wants.  Redhat does it.  It's possible.

A rock solid OS belongs to the people, not to some corporation.  The world is assuredly waking up to that fact.  The more Microsoft fights it, the more they have to adopt Open standards ... which fulfills most of the goals anyway.
