So, how much more vulnerable does this make HP with its upcoming split?
Dell doesn't care. They've been private for a couple years. No one's going to pummel their stock tomorrow morning.
Anyway, HP has much more to fear from HP than they do from the synergistic effects (lol) of Dell+EMC. HP is a total disaster, and is far more likely to kill itself off than die from consolidation around it.
