There seems to be some Sun-focused FUD and Linux-focused fanboyism flying around here and on Kirk's blog. Obviously, that's no way to evaluate competing solutions. We need facts. We need apple to apple comparisons of hardware and operating systems, where we can get them.

Of course, every /serious/ business can and should get into the details, but for the sake of argument, I invite you to compare a couple apples from the barrel: Sun Microsystem's Sun Fire X4150 (used by Kirk's site), and Dell's PowerEdge 1950 III.

They support /very/ similar hardware options (rack units, CPUs, memory, network, internal storage, out-of-band management, power, expansion slots, etc.), have roughly the same price depending on options (~$7500), and run roughly the same major software (Linux, Solaris, VMWare). Based on that one example, I don't see how Kirk justifies decrying Sun.

I could go on with more hardware or a light comparison of Solaris vs. Linux, but you get the point. Stop with the hyperbole and try presenting facts in a digestible format.
