Microsoft is already doing this. Shops can set up as resellers of Office365 - we have done this - and I kid you not - we make a grand total of $0.09 per month off each user we sign up. Nine fucking cents. So guess how much effort we put into it? I can promise you, everyone in the channel, from the large resellers, to channel partners, to the small shops fully understands that the end is coming for being able to sell OEM Office, Windows, Exchange, etc. SBS is already dead - it no longer exists and can no longer be purchased.
It's also a typical Slashdot response to say "selling people their own non-Microsoft based...." but it's also, with all due respect, completely out of touch with reality.
We don't really deal with small companies and their IT a lot - unless we have a reason to (for example, we look after a small accounting firm, because they're our accountants and I'm socially friendly with them) however here's them as an example. They require specific software for their business to function - there's no Mac option, there's sure as hell no Linux option - they need to use MYOB and Quickbook and System Release. Need to. Not want to. Not choose to. Need to. EVEN if they wanted to change, which they absolutely do not, every single one of their end customers would need to stop using MYOB. So they absolutely have to use Windows. There's no OSS accounting software they can use and they can't force all their customers to use it, so MYOB it is. System Release, the software which allows accounting practices to manage multiple MYOB clients, certainly doesn't have a Linux option on the table.
So how do you propose these people, and the literally millions of people like this, just change? Coz its just oh-so-easy to switch, here on Slashdot.
So not to get too sidetracked - I fear for those companies who still rely on pushing tin and selling Windows and Office to survive because Microsoft is going to go Full Apple on them, eventually and cut them off from the feeding trough.
