"No significant issues"...?
Except, of course, for the very significant issues explicitly described (and ignored) in the article:
"…after set-up seemed complete the Store still had 20 downloads to do, including key built-in apps such as Music, Camera and Photos…"
So the Windows Store is now replacing things like Windows Update, and becoming the only source of essential (formerly built-in) software tools. Not a good thing. Especially since Microsoft had originally said a Microsoft log-in would be optional (to use Windows 8). But you can’t access the Windows Store without a Microsoft login. I suspect that all UWAs (Universal Windows 'Apps') will come from the Store, and Win32 code (in ever-diminishing amounts) from Windows Update. Bottom line, you are now using Microsoft's flavor of iOS. Congrats!
"Cortana’s “Notebook” (the database of personal information which informs Cortana’s suggestions) is now in its final stage…"
Windows 10 basically wants to know everything about you.
"Now Cortana can be activated with “Hey Cortana”
And it listens to everything you say. Can you ever be sure this is truly turned off?
"When you type "Calc" in the Start menu, only the new app is listed…
Most of the core utilities are now UWAs. So using ‘Metro’ (i.e. the Universal Windows Platform) is no longer optional. Start throwing away all your existing software, because, as Microsoft has explicitly stated on many occasions, "UWAs are the future of Windows." (I'm not sure why they can say this over and over and still have nobody believe them...)
"…marked as a "Trusted Windows Store App"…. The same trusted note appears for other Microsoft apps, such as Music and Photos, which is a hint that the company would like users to perceive the Store as the safe way to install apps."
The Store is gradually becoming the only way to get Windows software. Sorry... Windows "apps." And Windows "users" are gradually becoming obedient, carefully-watched mobile 'monetization' fodder. Microsoft has been quite forthright about this in recent announcements. They even merged their Windows OS division and Cell Phone divisions! How can they possibly be more explicit: Windows is becoming a mobile "devices and services" platform, as carefully locked-down as iOS, as disrespectful of privacy as Android.
No thanks! Even Apple knew better than to screw up its desktop OS this badly. Windows 10 needs to fail, or basically Windows as a desktop OS is finished.
But on the positive side, it is "free" (as in beer, that is)...
