I use Windows at work and Mac OS X at home. I have been a Mac user since 1998 if I include my time with BeOS on a Mac clone.
I have used Linux, NetBSD, and Solaris at home, school, and work over the years. I have used OS/2 during the Warp 3 and Warp 4 years.
Yet with all the experience, especially with Windows, I keep finding my way back to the Mac and cannot imagine computing life without Mac OS X.
Ironically, and despite common assumptions to the contrary, I ultimately find that Windows is easier for programmers and UNIX is easier to use.
Anyway, I have my pet peeves and complaints with and about all operating systems and platforms.
What are yours?
Give a list of ten complaints for each operating system you have used at home or at work (for longer than a few months). Windows 95/98/Millenium count as one, as do Windows NT/2000/XP/Vista/7 and their server versions. Linux counts as one OS, distribution-specific annoyances do not count unless all major distributions have them. It must be ten complaints for each system, not more, not less.
I'll reply once I see a few comments. I try to come up with ten complaints about Mac OS X, Windows XP/Vista, Linux (in general), and Solaris. (I can add OS/2 if readers request it.)
