Microsoft Doesn't Deliver on Office 365

I love the new office don't get me wrong I have loved office since it first came out, but when I finished with my computers I usually sold them with the outdated software. Never dreaming someday I would wish I held on to every old copy of office I bought, because Microsoft doesn't even support a common not at all outdated O.S. with the new 5 devices office 365 (what is the point in buying it for up to 5 devices when I can't install it on 2-3 of mine because the O.S. that isn't even 25 years old yet is no longer supported). At very least they should offer customers the option to use an older version of office so they can get their full moneys worth. Oh & the non-profit donation Microsoft gives is a complete joke too, because again they require the non-profit business to buy upgrades for any O.S. Vista or older before they can install making a lot of computers useless to new not for profits with limited resources as it is. That's the equivalent of donating a game or software patch without the game or software it goes to.
