lol...you noticed the HP sign was gone, replaced by another sign, but decided your curiousity was strong enough to bother to notice the name on the new sign. You're real friggen helpful, dude. Dont' both posting again about it.
Nothing's really changed. The huge Compaq-size sign has been replaced by the puny HP invent logo, placed on some cement columns, here and there. I think that's done to be consistent with the other HP signs at HP's California buildings.
Unless they lease CCA14 and CCA15 to Shell? That's the rumor I heard last year :)
Talking about sign changes, what's up with the Cupertino campus? Some buildings look deserted recently. The red Tandem buildings seem empty, and signage is all gone.
