What tomuchtodo said. When I left Sun in 1995 I had 8,000 shares, which in 1998 would have paid off my house, and when I sold them when Oracle bought Sun after a reverse 3:1 split, the total would not even buy a new car. Can be a painful lesson, certainly it leaves an impression.
Heh, I was at Netscape when the Sun-Netscape Alliance was created. Tip of the hat to a fellow gray beard. ;)
