and HP are the top hardware vendors. Some interesting surprises for me.

This is not as surprising as it sounds.

There are thousands of people worldwide capable of
porting Linux to a new architecture, and the source
code is readily available. For a new processor
or new computer architecture, Linux is the obvious
first choice.

You pick an already supported architecture similar
to your own and make a few modifications. It's a few
tens to a few hundred lines of code.

As we speak, Linux already supports about 50 different
processor families, with hundreds of different
implementations.

Can you imagine the amount of money required to get
MS to port one of their OS'es to a computer of which
less than 10 will be sold?

MS used to support about 6 different hardware platforms. Now they only
support 2. They are after the millions of copies market. The list is only
the fastest 500 supercomputers, not all of them. And, oh my, Mac OS X
shows up there. There is a difference in the scalability of the two OS's.
