UltraSPARC came out in 1995, and Athlon 64 in 2003. I'm confused on how it could be late?

> - The MySQL purchase. WTF, this was horrible and stupid. The only interesting effect of this was to make Sun a target of acquisition for Oracle. [..]

I disagree with this assessment strongly. I believe Oracle wanted Java and only Java. All other Sun properties were collateral damage of the acquisition. It might be weird that Oracle now owns MySQL, but Oracle never cared about it. (Of course, both your and my assessment are mere opinions.)
