The article point out exactly the same cause pulling IBM from industrial giant to a corporation desperately seeking partnerships to survive.

I were in the IBM during 80's. They've good technologies, but few could actually get out of the secured rooms. For one they've visual development tools inhouse while the rest of the world is still using text editors. Later the Visualage initiative collaborate with Microsoft's Visual Basic to build a RAD paradigm. Then we asked, WTF, we had everything we need inhouse, why in the hell we need to collaborate with something with relatively inferior technologies?

The catch was that the top management didn't even know what's in IBM, and believed that other companies were doing better than us. They focused on market segments, and pushing PS2-386 even though 486 are out and became majority, because they thought "statistics show the major market is using 386". PC manufacturers like DELL should really thank them for giving them chances to grow and hit mainstream.

The downfall of IBM is a well known story, but executives in Nokia fail to learn from it.
