Oh who gives a sh$%....it's been over a year now, get a life or get therapy all of you who belabor this point. HP is dead, and so is the old US. Old HP is running the show, old US has the majority in size. So you both have one up on each other. As far as who bought whom, it doesn't matter anymore, it's a done deal.
Try to focus your energy on trying to fix what's broken and make your work lives happier (I know not an easy task). If you can't get over this, get help, or get a new job. This east vs. west thing is getting old and tired. It's not like if you keep bitching, they'll get a divorce!!
