^ Isn't that the way Microsoft wants to go (or already has) with apps like Office?
I'm not really bothered about that - I have 0365 home until 2020 for about $60 - which is cheaper than a single copy of office - is for five machines, has tablet apps, unlimited online storage and 60 minutes of skype calls.
At that sort of cost it's not worth thinking about (especially as it is a deductible).
