Would be nicer if they cut the price to $16.67 per user per year
They do a single-user version. It's £60 IIRC per year, as opposed to £80 or £90 for the 5 user version (I forget the exact price).
So it's more like you pay £50 for a home installation, then £10 per user on top. Of course, a single license is often enough for a family to share because you typically don't all want to use Word at once.
