Something that is unclear about the free W10 upgrade. If you have a retail license you may lose the "retail" part and be stuck with an "OEM".  Microsoft was lenient in the past when you replaced a motherboard or processor under an OEM license but I don't know if this will change.
 
 

I don't believe W10 will be the last- I believe that is what marketing likes to tell us to get up to take the hook, but I wouldnt be surprised after awhile when W10 starts to get stale in the market and competitors start sizzling because they offer a change that MS will trot out a new version to compete. 10 will be around maybe 10 years or so, but not "forever"

You are assuming we will all still being using PC's... I think MS is betting PC's are on their way out if you see what they are doing.. Maybe another 5 to 10 years...

To be replaced with what? Tablets are not good at all for creation of content, only consumption. You also find that new technologies often don't kill old ones. Like Mainframes, there are more of them in the world now than when there were only Mainframes. That doesn't mean there are a lot of them, compared to desktops, but the market has not gone away.
 
Likewise while mobile gadgets are fun toys, they don't seem to be doing anything to kill the desktop/laptop/server market. It isn't growing, but the two states of a market are not grown and death, it can be stable as well, and is.
 
That aside if everything goes mobile and "to the cloud" you know what the cloud is, right? It's a bunch of Dell or HP or IBM servers running VMWare or Hyper-V or Xen. It's all regular computers on the back end, tons of them.

Sorry, can't type well today, my neural implant crashed.

Maybe you should write to M$.

I should have been more specific, I should have written desktop PC's. And btw cellphones and tablets have reduced and are still reducing the desktop PC market. M$ is just responding (rather late in the day) to market trends.

Yup M$ want to sell their servers, they don't want the market to be dominated by android and linux for instance.

Btw people are still using typewriters and fax machines but there aren't so many around.
