Are they just skipping 9?
Yep. It seems they're aware of the reputation that all even numbered Windows releases should be skipped, and have decided to solve the problem not by working to make a good release now and another good release later, but by cheating and changing the number to skip ahead; truly brilliant ability to miss the point on Microsoft's behalf.
I dunno, it's a really stupid thing; they claim they wanted to go for "Windows One" to match other branding, but that they can't because Bill Gates already created that one (the anecdote was ****ing hilarious by the way), but that makes no sense as Bill Gates created "Windows" or "Windows 1", and in terms of branding "Windows One" isn't the same thing. Besides which they seemed to have no trouble with naming their games consoles chronologically as XBox -> XBox 360 -> XBox One.
So really I'd rather they'd named it Windows One, as it'd make more sense than just skipping 9 for no reason at all.
Mini-rant on that over, it looks like Windows 10 is shaping up to be the same kind of release that Windows 7 was to Windows Vista; in other words a great big question mark over "why didn't you do it this way in the first place?". I would have thought that literally anyone could have told Microsoft that Windows 8 wasn't going to work as-is, and a hybrid Start Menu, along with Metro apps in windows were extremely obvious ways to make it work for everyone, but apparently Microsoft is really gifted at finding people that won't challenge higher ups who don't really know anything about their target markets. In fact, all through the beta/preview/leaked releases Windows 8 was being panned for its awkward usability, yet Microsoft did nothing to meaningfully correct it, that is until now that businesses and users have totally failed to switch.
Still, it'll be nice to finally be able to get the Windows 8 underlying technologies, but with Windows 7 usability. I do really wish they'd finally do something about desktop and quick-launch shortcuts though; every bloody installer tries to recreate them (or just does it regardless, Apple is guilty of this actually) and it's horrific. If you let every installer create a desktop shortcut then you may as well not have a desktop. Old style installers, dll hell and registry corruption would also nice to see banished, but my prediction is that we're stuck with those for at least fifty more years.
In fact, I recently tried ElementaryOS; it's a pretty OS X like Linux distro with a lot of great features of its own, one of which is a total lack of a desktop folder! You can still have a background image, but you can't put icons on the desktop, it's total genius. Might sound like a silly issue, but I've been dealing with messy desktops (not just my own, as I've gotten quite tidy over the years) since Windows 95 and Mac OS 7! Maybe it's just a pet peeve, but I want an end to it!
