How to get comfortable in linux as an ex-windows user?

I've been using linux full time for about 8 years. Now and then I help someone else migrate from windows to linux. Because I don't often use windows, I often find myself forgetting some of the differences between the operating systems. I would like a guide that I can give to such users, to help them get more comfortable with using linux. The guide should include things like the drive mounting systems (C:\bar\ vs. /foo/bar/), and software installation. There are lots of guides out there called "migrating/moving from windows to linux" or similar, but nearly all of them seem to be full of linux propaganda, or installation instructions. That's fine for other purposes, but I want a guide for someone who has already decided to move, (e.g. because they like the concept of open source), and for whom the system has already been installed. So a post-install "I've moved from windows to linux, now what?" kind of guide that covers *practical* differences (i.e. not philosophical or highly technical) that an average windows user (Someone who uses a computer for websurfing, document editing, movie watching, game playing, etc.) might encounter. Do any such guides exist?
