I have seen it, they are comparing SAMBA on a 2-CP Z900 to a 2 processor 900Mhz xeon box. Of course it is going to be more expensive, if the only thing running on the z900 is samba. This is a common slant to the us vs. them picture. While there have been a few documented cases where some shops buy a z-series box for just linux, it is much more common to add IFL's to an already existing mainframe infrustructure. Compare *those* costs, and it becomes much more competitive.
Whew! We can finally replace our mainframe... and with a dual 900Mhz Xeon!! Who knew!! I may have it water cooled just for old-times sake though.
