Does anyone know what macs are running iCloud, iTunes Store and all those massive storage facilities in North Carolina? I'm assuming Macs are running them and I imagine they would have to be pretty powerful. So what macs could it be, mac mini server, xserve or mac pro server? I'd bet it is either an xserve or mac pro server. And now that the xserve is dead, that only leaves the Mac Pro. So if Apple is serious about killing off the Mac Pro what are they going to use to power their high end facilities?
