Yeah, no, I'm still perfectly fine with Windows 7 and haven't even upgraded and won't upgrade to Windows 8, so I definitely have no reason or desire to upgrade to
Windows 10. Yes, they're apparently skipping Windows 9 for some reason.
(EDIT) From one of the comments under that article:
"I've read that it's Windows 10 instead of 9 not because of marketing, but because there is tons of software out there that checks that it isn't running on Windows 95 or 98 by checking that the OS name doesn't begin with 'Windows 9'. As a software developer, I find this explanation entirely plausible."
Don't know if that's true or not, but I could easily believe it. (/EDIT)
