We have the linux challenge, we have the Break a Leg stuff, now we do the most illogical thing possible.
A WEEK OF ESOTERIA!!!!!!!!!!!!!
The idea here is a week in an OS of your choice that isn't Windows Linux or OSX. I'll border BSD on it as some BSD are rather.... odd. But the more wierd the better. Take an OS that you have an interest in, Haiku, AROS, Temple, and run it for a week. Take screenshots, do your stuff in it, you do you booboo. If you have an OS that you recently found then post about it here as well! Maybe someone will try it for a week!
I for one will run Icaros on my i7 laptop, possibly for forever, but in dual boot with windows 7. I'm relatively familiar with it but I want to dev for it and build stuff for it. Hopefully I can do all that I need to do just by building apps.
