Alas
Well "Anonymous Coward", you clearly don't know much about operating systems. Maybe you are thinking somehow that they are planning to run Windows 95 on the mainframe? The NT family of systems has been running successfully on big iron a lot longer than Linux. You may recall that Linux used to be a single-proc-only OS. NT, BSD, Linux and Solaris are all perfectly able to drive large enterprise server configurations.
But here's the thing...
Why are register comments so bad? The Register is highly respected. It's articles are read by top people in the field every day. And yet, the commentary is like stuff kids write under a YouTube video they didn't like. It's disappointing. The Register could be a forum where top people discuss and debate.
I'd like to see them moderate the comments much more strenuously, but I know they won't because it has become a sort of amusement in itself, like the Jerry Springer show. Oh look at the Windows and Mac fanboys insult each other. Hey, someone spelled Microsoft with a "$", wow never saw that before (yuck yuck).
