IBM is where good companies go to die.
In a midnight-stealth deal, the CEO took the IBM offer without even waiting for a competing offer from Microsoft, when most of Rational's customers use their tools on Microsoft's platforms.
Now, instead of providing additional revenue to IBM, Microsoft will improve Visio's UML tools, and bury Rational Rose and the rest of the software suite without so much as a whimper.
Anyone remember Notes? Sure, the CEO and the board get rich, but for the great developers at Rational, I expect most of them will end up in Redmond in the not too distant future.
