I am a little surprised at the lack of knowledge about IBM in this thread. Most people reading this have used something made by, or designed by, IBM today. It could be the scanner and backend software/hardware at the supermarket (IBM invented the UPC). Or perhaps the ATM (invented that too). They are into many industries, and are well diversified.
Just last year their value surpassed Microsoft's for the first time since 1996. All without selling a single laptop.

The lack of IBM knowledge here is just pure ignorance. While it may not seem all that exciting, their stuff just "works".
Actually, they wrote the book on it. Fairly detailed in fact.
