I for one am pretty upset that original surface RT and Surface 2 users are getting screwed over with Microsoft not updating devices to Windows 10.
.
I think the word "Screwed" puts your post at odds with what is really happening Stefan.
The Surface RT and I suppose the other RT devices will become a bit of a backwater, MS had to try the idea, but most would people would say overall it wasn't a success.
I bought my wife a Surface 2 and she loves it, it does what she wants it to do, and it will carry on doing what she wants it to do, it sounds like it will get upgrades to help it tie in with 10 is going, but it isn't going to get full blown 10, but it will still work.
I once bought a Phillips CDi, this was a fantastic bit of kit, well in advance of the alternatives of the original Xbox and in some ways only just being surpassed by the Xbox One in terms of all round entertainment, I paid lots of money for it and the games/media that was available.
It turned out to be a dead end, never got updated, not once, no more games/media was released, but did I get screwed, my family got lots of use out of it for many years, and it only just stopped being a good CD player.
Did XP users get screwed, it's now dead, there are still people using it, happily on devices that cannot be updated, they still work, but from the futures point of view they are dead.
Microsoft cannot stop 10, it is a juggernought and the future for the company (And many of us) and they cannot afford to get it wrong, but they cannot afford to go down every blind alley, they aren't dropping support for RT devices, they will still be supported with some updates, they will get a makeover, but maybe not full 10. RT devices will still work.
So the use of the word screwed is perhaps a little bit harsh.
