Great, I'll be busy prepping an Android VM appliance for this that I can install on every machine I touch. Probably a good idea to isolate Office code from the real OS anyway. Hope I can get printing to work.
I wonder why you're being downvoted for a hackish idea on a site called 'Hacker News' eyes rolling. I think the idea is interesting - not sure how to make file sharing work though, can you mount SSH drives from the local network on Android? Or do you want to just use Dropbox for that?
Given there is Android for x86 (atom), it should not be that hard indeed.
