I was thinking the other day... I haven't seen too many Xserves around, and they seem to update them on a very rare basis. So why do they even bother with that line; it's gotta be a drop in the bucket for them, profit-wise? So I thought, Apple *might* be using a few servers in their operations (), so do they use Xserves? If so, they may be their own best customer, and by having their own server line they don't have to buy servers from the competition. Thoughts?
