I was a OF user for years before switching. I got Office 2010 because of a client and like you said after couple of weeks of trying was enough for me to like it. The workflow, the mouse over preview's in the ribbon and shortcuts is such an improvement. Now I can't see myself switching. One more note, money shouldn't be the reason not to switch, it's worth it if you use it for business. For personal use, Google (which I use too) or LO will do it.
