There's some forthright discussion of speed and reliability issues in Mac OS X at http://www.atpm.com/12.08/paradigm.shtml There seems to be general agreement that OS X through 10.3 was plagued by stability and speed problems. I pointed out that this had generally not been previously admitted in the Mac literature, as it isn't recognized in your response here. There seems to have been improvement in 2005 and some regression in 2006. If the consensus represented in that unusually forthright discussion was that OS X just became usable recently, it is unlikely to have become a speed demon or to rival Windows XP in stability in the time since.

When I played with Omni Outliner on a Mac 6 months to a year ago in the Apple Store in LA, it was painfully slow. I don't think Mac users on the whole are objective observers and commentators on their computers' performance.

Beg your pardon. That's nonsense.

Over the last 2 years, we had 3 Macintosh
machines (OS X 10.3 and 10.4) and 6 Windows XP machines here. Some of the machines were
new when we bought them, some notebooks were second-hand. We use them mainly for
writing, translating, email, web (browsing and design), info storage, desktop
publishing, image editing and graphics (diagrams, flowcharts, sometimes
illustration). All the tasks are done both on Windows and Macs (except for
illustration as we only have Corel Draw).

And our Macs are more reliable than the
Windows machines. We had only 2 crashes on the Macs - both on a Powerbook that was - I
think - 4 years old. 2 of your Windows machines crash regularly, one at least once a
week. The other PCs are fairly stable (but they restarted every morning, the Macs
usually are not turned off at night).

In our experience OS X is only slow on machines
it was not designed for or that are faulty.

We ran OS X 10.4 on the used Powerbook (800
MHz, 512 MByte RAM) and could not complain about speed. Ulysses, Tinderbox,
Devonthink and Scrivener are about as fast or slow as Microsoft Office or
OpenOffice.org on a 800 MHz Thinkpad running Windows XP.

And that's not only my
personal experience. That's the experience of a couple of Mac and Windows users I
know.
