OK, I got baited... So I'll only contribute once...
I read TheRegister for IT news like I watch Fox News for politics. They get a story and hype things up a notch for my taste. I take what their articles say in combination with news sites like ArsTechnica, WinSuperSite, Thurrott, TheVerge, ZDNet, and Engadget, etc for a better view on any one topic. Many of those articles are written by developers, IT admins, and end users, for a balanced view.
I've been running Windows 10 since it was released to public, albeit the slow build, on my own personal and work production systems. And I am excited by what their trying to do.
There are lots of changes to the UI yes, there are changes to how they will roll out updates, and builds going forward, so many things, beyond any one article or convention you watched.
As many articles have stated, they are going for something now even Android has not achieved- a consistent Windows OS ecosystem across devices, with minimal fragmentation (OS versions in the wild all being the same), and consistent development of apps for all those devices, from now on forward. On Windows Phone for example, they are removing the Phone Company from preventing updates, as is the case with Android, but giving people the choice of device, something Apple doesn't offer.
Also what they are trying to do is make Windows a central OS that can give a proper interface/GUI for the device its on, from a Rasbery PI to phone, to tablet, to PC, etc.
On the Dev side, this is really hard to achieve, changing almost every aspect of the OS. While working in a simple app recently, I saw a paper on the changes they were making all the way to drivers in the kernel so that even the driver can be made to work for hardware in a Phone all the way to a PC. All of this while preserving existing apps and drivers functionality. I hadn't read that in the news, or on a dev site, I found it on the MSDN accidentally. There's a lot going on not being covered that has lots of potential in the long term.
One nice thing in the Technical Preview is that they seem to be prioritizing feedback more than ever before. And they have actually applied suggestions between builds.
So I can understand the timing because I see how much they are trying to squeeze into this release. I also was not surprised to see how it will be spread out. But seeing as the update schema will be changing as well.. I'm eager.
And none of this touches the server side stiff going on, which is really cool.
As a disclaimer, I've had all this IT stuff back to the IBM TSR-80, to Android, Apple, MS, etc products today.. I'm tech enthusiast, not a loyalist. I just like to see how technology grows and achieves over the years. Everyone has their good and bads.
