It is not specific to HP, but to the top management style of that era; I know multiple companies that went through similar things, some from inside (can't give names), it was a similar story: moving from deep technical expertise to soft "software and services" mantra that fits weak CxO. At the same time other companies that had more technical CxO did much better, these are the companies that are on top today.
There is no much differentiation in the IT services space, lately they provide worm bodies to clients and not much more, or nothing at all. There is no competition, there is no differentiation, it is the place where old elephants go to die. And the CEO of HP at that time had the vision to go there.
