Actually, this is a long planned merger. And, just like the code names for calculators, HP has dropped hints by way of the calculator suffix:
C series - Compaq
S series - Saturn, but cars didn't fit HP image
B series - IBM merger (fell through)
X series - Xerox merger to make calc/copier combo
E series - Exxon. Backed out after Alaskan oil spill
e series - soon to reappear after eBAy takeover
D series - Dell, but regulators wouldn't approve
G series - Gateway, calcs with black and white shift keys
As a condition of the takeover, HP was to drop all RPN devices, in particular the well loved 42S. We'll see which suffix is next and guess the next corporate target!
