The final stroke for blades going commodity

This week, HP decided to buy RLX, one of the pioneers of blade servers. RLX had actually been out of the blade hardware business for awhile -- now they make blade management software. Nevertheless, this move is the symbolic final stroke of blade servers going mainstream. I remember how cool blade servers were when they first came out and RLX blades were the first ones that really offered a viable business solution. It was just cool as heck to be able to fit 10 servers in the space that had previously only fit two similarly-powered servers. All in all, I think blades are still underutilized in most IT shops, even though HP, IBM, and Dell all have extensive lines of blades now.
