I am rather lucky that I have moved them to open office about 12 months ago with only minor headaches(and it can open office 2007) (it was actually this move that lead to the linuxification in the first place, and a guts full of windows being crap) as far as weird software goes there is just heaps, but for the time being those machines are field instruments and will be keeping windows, do tools exist for importing emails etc from exchange/outlook express to linux mail clients?
