Simply an opinion but I will bet on pure software running on flaky cheap hardware providing more performance and reliability per unit cost in the long run. Ultimately the real win will be scalability. So for the same cost you build a system of many more commodity components you just make sure that your software can deal with the problems. It seems to be working for Google.
