We have two Linux boxes which act as Internet routers, mail servers and development systems. I have a huge Pentium on my desk running Windows, of course, but with an XWindows client to connect to the Unix boxes as well. Opposite me my wife Heather has a Win98 box, which also runs as an X-Windows client. There's a notebook running Windows 95 and another running SuSE Linux, and there's also a Mac here too. I think they are amused by it, at least that's the feeling I get when I talk to them.
American writers tend to be extremely professional in what they do and what they say.
I get the impression that many of them find it something of a breath of fresh air to read a book that talks to them as if they were a friend down the pub. Of course, there is always that American fascination with English sarcasm as well, and that comes across in the books too. To be honest I have only ever been slated once by an American reader for my writing style. A young lady, with strong political beliefs on woman's role in society objected to an example I had used earlier on. She didn't like that and made no bones about it.
