Coming late this summer, maybe early fall. I've been participating in the Insider Technical Preview. It's a nice update from windows 10, I put on an old HP system I have that doesn't have a lot of ram and an old processor and it installed just fine so it should be really compatible with anything that is no older than 7 or 8 years. It boots to the desktop and has a start menu which was a huge factor for those who didn't like Windows 8. The start menu is not quite the same as windows 7, but it's configurable and most things are where you expect them to be. It's fast even on this old system. I just got the new Project Spartan browser and it seems ok, some of the sites seemed slower, and it did lock up on me but this is it's first release so bumps are to be expected. The good news is that for most of us the upgrade is going to be free.
I guess 9 was so crappy they just trashed it and moved on to 10? Thank goodness, 7 and 8 were bad enough.
I went to the dark side 6 months ago...Macbook Pro. Not as "more hassle free and more intuitive" than Windows as some Apple aficionados would have you think...but I'm happy with it. Certainly boots up faster...but who cares how fast it boots because it never crashes either.
Scott, my OS progression was DOS to 3.1 to 98 to XP (and NT/2k) to 7, which allowed me to avoid 95, Me, Vista and 8. It sure does seem like every other Windows version is crap. What I really hated about 7 is the total lack of control. M$ forces you to use the layouts they anticipate most users will like, rather than giving power users a choice without breaking the system out.
