I've been thinking for ages about moving to Linux. Most of what I need (internet, word processing, home accounts) is freely available. It also opens up possibilities for playing with some interesting new technologies. I just need to ensure that all my data can be transferred across. There's also the issue of using my peripherals. I just bought a Canon printer that is not officilly supported in Linux, but I found a comment on a forum that suggest it might work. See my del.icio.us links.
I will still have at least one Windows PC in the house if I really need to run Windows software. The kids use one for web and some old games.
