There are just so many different ways to say the same thing over and over.
I think you have covered every single one of them plus added a couple of extra's here and there.
You are free to do whatever you feel is right for you.
The other 99.9% will do what they feel is right for them and will be happy with the free upgrade.
I rest my case and bid you a good night !
I think I'm gonna go out tomorrow and purchase something for $120 that I already obtained for free.
Tim Myerson said something a while back about giving pirates 'something special' - I equated that to a cheapo-special... so we'll see after the free period ends - if MS has not reached there goal of number of devices - whether that materializes.
Also they should consider relaxing the Device ID criteria - some report that even BIOS/CMOS changes can deactivate - this is gonna be problem after Aug 2016 - albeit a small percentage will be affected.
That 'something special' for pirates is that they'd still be able to update to 10 but will end up with just as illegal windows as they had before. I have no idea why they had to reiterate that as none of that stopped pirating before. It may be trap though, to catch some of illegal registration numbers and get them out of circulation.
