Friggin ridiculous naming choice. The 10 shows there will continue to be more versions, so why skip 9? I would have even preferred just Windows, though that would make sense if they just sticking to that version, with constant updates.
I think I will go ahead and buy a Windows 7 laptop, since this isn't launching til next year. Though if they offer a free or discounted upgrade, I probably will upgrade to W10. Looks like a definite improvement over 8.
