Software smuckware, the whole point is they are not working right and nobody is there to hold the google boys hand and smooth things out, any cost savings in power consumption and price of the hardware may well get eaten up by the cost of debugging this fiasco. Google made itself on low cost low maintence intel servers looks like they are getting a little reality check, microsoft may be slow but they are not stupid eventially they will take a wack at google and keep wacking untill it hurts.
