As an alternative viewpoint, the disadvantage of going any MS Word route is you remain to some degree or other (even if it is only the odd conversion thant won't work) remain locked into proprietry software.

Break free where you can! I must admit I still have Win 2K on my laptop and do have the occasional need for a bit of Win software but I've no regrets in moving onto Linux (Suse 9.2 in my case which cost about £50 I think) for my desktop PC.
