Tons of fantastic analysis and viewpoints over in Microsoft's Windows 10 TP forums. Here are a few that caught my eye recently, other than @NoelC's.
On the near-requirement to log onto Windows with a Microsoft Account:
Currently, however, there are many cases where, even after stepping through the non-intuitive procedure to make a workgroup account that is not tied to the MS Live ID, it is broken by MS Live ID requirements at later date. This just happened on my Windows 10 evaluation build 10041, when trying to submit feedback, and being required to log on. The original account management on my system was automatically migrated to my Live log-in credentials, and even after changing local policy to use Ctrl-Alt-Delete secure log-in, I was unable to log in on that original account.
I do not--repeat: do not want to use the same password (or even the same user account) across machines, and across all of the forked workflows. This violates a cardinal security best practice of not using the same password for everything you use a password for. That is simply a treasure trove for hackers, spear phishers, social engineers, and other unsavory nosy entities.
On the stated reason for eliminating the Start Menu in Windows 8:
Microsoft claims they got rid of the start menu because it was only used 6% of the time. I don't think I spend more than 6% of my time in the bathroom but it is necessary to have one. There is no rule that 6% = 0, yet that is how they chose to interpret the data.
On the excuse given for eliminating Aero Glass, that it consumes a lot of resources and battery power on mobile devices:
Aero in fact does not require a lot of resources. In fact there have many people here who have posted links to the Aero requirements and many of us have made our own benchmarks and linked to others as well. This is patently false.
My Note 3 phone that I had over a year ago had a Quad core 2.4Ghz processor with 3GB of ram on a 5.7" screen. Phone hardware has had the ability to run Aero for more than 5 years now. While it is true that it would consume more battery life even there the amount would be almost negligible. To the point that you hardly notice it.[...]
Theres a couple of solutions.
1. Bring back Aero and install a larger battery.
2. Allow it to be defeatable and default to off on devices that need it to be.
3. Don't use on mobile devices at all and save it for the desktop.
The unified OS MSFT is trying to design isn't about the UI so much as it is the core. In other words as long as Metro app A can be installed from the store on both your laptop and phone then MSFT has achieved their goal. How A appears on individual devices is irrelevant and actually not possible to unify in the first place. How to you take into consideration a difference in screen size or resolution. Metro app A might look great on a 4" phone and total rubbish on a 27" 1080p monitor.
Point is choice is the correct answer here. Its what MSFT has always done in the past (even if eventually one of the choices fades out) and for some reason they aren't now. This is why windows 10 (just like 8 and 8.1 before it) will indeed fail and not achieve what MSFT needs it to in either the desktop or mobile markets.
[same thread] On the Metro interface being so unpleasant to use that people end up using their PCs less:
I too gave 8/8.1 a try for a combined time of about a year. I didn't want to be accused of the "youre just not giving it a chance" ****. After a few weeks I realized that I was using my PC less often which was a problem for me. I soon looked into other solutions like Windowblinds and hacked visual styles (the xp one worked well for me there). after about a year I had a need to format and decided to just go back to 7. I have no idea what I was thinking using 8 in the first place lol
(Personally I gave up on the newly borked pseudo-Start Menu and installed Classic Shell on the TP again. It was shocking how much easier and more fun it was to use. No more hideous solid-color rectangles taking up half of my screen when I open the Menu. All Programs actually opens when I hover over it, and the Start Menu actually closes when I hit Escape, and I get my Recent Items list back.)
A lot of good stuff being said over there. You end up shaking your head at the Win10 defenders who just don't seem to get it. It's like they're empathy-challenged, unable to understand how anybody else could possibly prefer to do things other than THEIR way.
