2009: Oracle buys Sun Microsystems for $5.6 billion (net of cash).
GeoCities... has... a bunch of servers? There's no lock-in (people can move anywhere else with almost no barrier). They sell a highly commoditized product with no differentiation (in fact, they were competitively disadvantaged, even in 1999).
One was a much dumber purchase than the other. Time will tell how smart the Sun purchase was, but I'm willing to bet it will be a lot smarter in hindsight than Yahoo was with GeoCities.
