Some of that is undoubtedly true. Most, maybe. However, some are clearly Windows-only problems, and Dvorak is so focussed on Windows that I sometimes wonder if he knows that there is anything else out there.
Actually, I know he is aware there's
something else out there, because from time to time he gives it a bashing - it's usually Apple, but ISTR him having a go at everything from AIX to Solaris. Not my favourite columnist.
