 <p>I usually use an <strong>Apple Macintosh</strong> to create these pages and the images, because I much prefer using <em>Mac OS</em> to any of the variants of <em>Microsoft Windows</em> and none of the other alternatives are practicable for me. For a few years I used <strong>Debian Linux</strong> at work, but now we have Macs there too. Anyway, it is not worth trying to explain why I use a Mac, although I suspect that anyone who had also used both <em>Mac OS</em> and <em>Windows</em> professionally for hundreds of hours or more each might be able to hazard a guess. Fortunately, perhaps, more people understand the difference since the iPhone.</p>
