Technology companies tend to have very fickle relationships. For instance, Microsoft helped launch Apple, worked to kill the company, provided money to save it, and then got its butt kicked by it. Dell first partnered with EMC, then competed with it, then bought it -- and the CEOs remained friends throughout. Dell and HP have had a rather interesting relationship as well. Dell used to resell HP printers, but after HP bought Compaq, the firms went to war. However, with HP now split from HPE, growth now lies in very different areas.
