ARM does have promise though, its just not in Snapdragons. As noted, the primary issue in Supercomputers is bandwidth (so that the processors can talk to each other).
Calxeda for example has spent a lot of time trying to solve this interconnect issue. Each Calxeda card is composed of 4 CPUs. Every CPU has 8 10Gb (aka: 1GB) ethernet links, 2 8xPCI connections and more.
Its a relatively young project, but they're moving towards the right direction. There are rumors that Facebook is deploying a Calxeda server.

OK, I'm sold.
