I can think of worse companies to try an absorb Apple…
But not many. IBM has repeatedly shown poor internal management and co-operation between sectors of its business. Apple could suffer severely from that mismanagement. They also soffer from the old apple “Arrogence” when creating home computers, with price/performance worse than most PC companies, and Apple. It would also be the death of Apple Servers, since IBM has a much more firmly established Linux, IBM-Unix, and WindowsNT based server division. Because of IBM’s wide range of options for hardware and software, there is also the serious possibility of interference with Macintosh development.
There are some positives however. Apple could take advantage of the superior IBM components in the systems. Hmm, a company that not only makes the computer, OS and primary applications, but also the Processor, Hard Drives and Memory. Now THAT’S vertical integration! Also, it could potentially lead to business apps (Client side and consumer applications most likely) to be ported to MacOS X, tighter integration with established business systems, and the conversion of IBM Home Computing stores across US and Canada into Apple Stores.
Unfortunately, all of those would require a fair bit of co-operation between IBM and Apple, something not likey to happen is Steve Jobs’ ego has to answer to IBM stockholders and management. There would also be substantial competition between existing product lines, like NetVista, Aptiva, Thinkpad and IntelliStations with the existing Macintosh Line
I think this should probably be kept in the perennial Apple Buyout/Merger roumour category. It makes more sense than almost any other buyout rumour, but I think the consequences for Apple would be dire in all but the rosiest of circumstances.
