Re: But
I largely agree with you, but you're a bit out with your volume agreements. My previous employer had an OVS agreement and had 250 employees. And believe me, an OVS agreement is useful when it comes to rolling out new versions of Office etc. without having to purchase, install and activate hundreds of individual copies!
Other than that, I agree. And the problem (largely) IMO is the cost of the OS. When you're making and selling a device for a few hundred pounds, the difference between a free OS (Android) and a £100 OS is quite sizeable.
