I'd buy IBM. IBM's business has always been service and their as good as or better than anyone out there. also due to the Enron FIASCO, the Price waterhouse, the Arther Andersons all these major accounting firms w/ Professional services divisions are going to be forced into some major restructuring.
IBM is sitting pretty if you ask me.
edit let me rephrase that, by Service, i mean Professional Services.
Their hardware sales is just to get them in the door to do what they do best to earn money, that's in customization etc.
