>>The thing that gets most people is just that, 'A Subscription Model'.
They haven't stopped selling perpetual licences, either personally or for enterprise. I personally like the subscription model because it's perpetual updates and they throw in enough extras such as online storage, installability to five devices (from iPad to Desktop) that I find it well worth it. But the old sales model is still there so adding a new choice is okay.
>>"Stop paying and bang goes access to your documents. S*D that for a game of soldiers.
I don't know where you got that from, but this is not the case. Whether you pay for Office 2013 via subscription or a one-time cost, they both use the same document formats and you can save them to anywhere you like. It makes as much sense as saying if you uninstall Office, your documents are "bang, gone". Well no - you still have them, and if you've decided you're not going to use MS Office ever again, you can always save them as ODF (or set that as your default from the start when it asks you which you want on install). Heck, you can even just install LibreOffice and open them in that even if they are OOXML. LibreOffice have done a stirling job at supporting MS formats. But the point is, none of this has anything to do with Office 365. You don't lose access to your documents when you lapse your subscription. If you're somehow confusing this with Cloud storage, well that's no different than if you rented hosted space and didn't remove your documents from that after stopping paying for the service. It's not like you miss a payment and your files get deleted, or you're ever stopped from copying them off there.
Anyway, the person I replied to was saying that you couldn't access your documents offline with Office 365. I'm making a guess that they were thinking of Office Web Apps (now called Office Online) which is the competitor to Google Docs. But whatever, they weren't correct about Office 365 - that's just payment by subscription, plus some extras.
