Actually, I chuckled a little when I read this, as my roommate just reverted to Tiger from Snow Leopard. After he upgraded to Snow Leopard, his computer picked up a host of problems (eg poor compatibility with some third party audio equipment, unreliable airport under a heavy load, a few random logouts--which I've also been getting). Additionally he was just unhappy with some UI changes between Leo and SL. His thinking was that he'd rather use Tiger, since it isn't as bloated as Leopard, basically as fast as SL, and virtually bug free.
