Perhaps one of the most well know, intelligent, thought out, and well written pieces on the differences between Windows and Linux (and why users should or should not use Linux), this CC-licensed document graces many a signature here on the forums and shows up in many posts as a response to typical "Linux can't do 'x'" threads.
However, it is four and a half years old.
It was made before Vista and Ubuntu 6.06 graced the world. It came out even before KDE 4 and when Gnome 2 was still going through its growing pains. OpenOffice was still at version 2.0 and Firefox was at 1.5. There were far fewer drivers, no iPod support, and Grub 2 was years away from stability. It was a very different time for Linux and for Windows.
I feel like the general idea is still very true. Linux is not Windows, people do expect that and walk away disappointed, the Linux culture is unexpected, etc. However, some points are less true now. For example, there is a part in Problem 5b about playing audio files and ripping CDs that expects the command-line to be a factor. Why wouldn't it? This was before players like Rhythmbox and Amarok were good, but they are now.
So, my question is: is this resource out of date or does it still feel relevant? Should it no longer be referenced, should it be updated, or is it fine the way it is?
