So you are including the web-lookup aspect when you say Linux has most
comprehensive documentation? Just curious, would you make the same
statement for the docs that ship with the OSes, comparing Linux against
the (latest versions of!) non-Linux OSes?
Often (not always) the Linux docs are a bit shabby since documentation
tends to not be the most exciting part of OSS. I can't really say which
is better overall (shipped-with docs for Linux or for non-Linux) since
the features are far from 1-to-1, but Linux docs certainly can be
dissappointing at times...

Linux works well on these SMP boxes for userland apps, but when it
comes to measuring "multi-cpu scalability" the benchmark seems to be
multi-threading kernel activities (e.g. I/O) and not userland
activities (e.g. rendering that just needs CPU). Your remark seems to
be a bit sweeping here; I don't believe Linux scales well (in the
kernel I/O sense) on >4 CPU boxes, right?
