Who needs it? You can spin up another Rackspace buying some commodity HW and SW. There is no exclusive "technology" that is available to RAX and the premium on its pool of talent is not worth paying 2X 3X the price for. These are just a bunch of very good techs. So you hire a bunch of good techs, a knowledgable storage guy, infrastracture engineer etc.. without shelling out 3 times the reasonable value at which this baby is trading.
I am sticking to my short here till 12-13. Dont care for upgrades.
