I hope these costs will be added to the energy bill of the consumers, so that the 'cheap' nuclear energy will be honestly valuated against those 'costly' solar sources.
Without cost for the enemy it's not a war.
1) People 'know' the previous Windows because it's what they are fed to eat. Every few years this is completely changed, that is why Vista and W8 failed. Show them a simple KDE or XFCE Linux install and within minutes they will know their way.
2) Who cares what you 'want' to screw around with. Any decent admin can find out how to get Wine runnning and port the oh-so-essential app to it. After that people will be very pleased because in most cases it will run better> than before.
3) If your problem is 'serious' bug reporting then try it on a Windows machine and see if it produces the same problem. If so, report that. Also, consider switching to an opensource alternative. They mostly have their bugs fixed within hours or days after reporting, certainly if they are security related. Compare that to the same bug reappearing in MS-Office for year after year, even across major releases.
So stop, Linux is fine for most people, especcially for small business desktops that run the same app all day. The big advantage is no vendor support, but real support.
And eventually, the threats that Microsoft makes when an OEM doesn't put Windows on everything will not have enough teeth to be effective.
It's not only the OEM that are threatenend. I heard stories about a big MS client that was making motions to move away from the lockin, being told by an account manager of MS that a lot of unpaid licenses were 'discovered' in his company. If he would upgrade to the next cycle these would be 'forgotten' about. Needless to say this client took the hit and now decided to move ALL his stuff away.
Clients have been harassed so long now that they are determined to escape the embrace and never come back.
