This time, however, Windows 10 is looking better than any OS I've ever reviewed, and it is largely because Microsoft did two things I've been requesting since Windows 95.
I'll share my thoughts on these "features" and Windows 10 in general this week, since we now know it is showing up two days after my birthday on July 29 (I think I'll still call it my "birthday present"). I'll close with my product of the week, an offering that reminds me of Bill Gates' house.

Microsoft's 1st Strategic Mistake

The Apple fans, even inside my own company, as well as the Unix and OS/2 fans, wanted me killed, and I became really famous (and surprisingly wasn't killed).
However, the first time and most every time I sat down with the Windows folks, I pointed out that they had a critical strategic weakness they had to correct. I'd been a competitive analyst for years, and one of the things that job entails is looking for things that either could enhance our firm's success or cause the firm to fail.
The thing I pointed out was that the PC industry, including Microsoft, lived on churn. In other words, it wasn't new sales but hardware replacements that increasingly drove the market. Windows was painful to upgrade, but it was excessively painful when you bought a new PC.

It could take up to a day to get anyplace close to where you were on the old hardware, and people started locking down their PCs. I can recall talking to an IT manager at Intel who said employees were refusing new PCs, because they didn't have the time to get them running. When that happens at a tech company, you have a problem.
The other issue is that if it is really hard to move to a new Windows PC, then moving to an Apple PC isn't that scary, because you have to pretty much go through the same mess. However, if you spoke to an Apple user, Apple migrations were drop-dead easy by comparison. Apple understood that churn was important, and it didn't have that problem.

Microsoft's 2nd Strategic Mistake

A related issue was the fact that if you were part of the beta program for Windows, you could install the beta product over your existing version pretty easily -- but when the beta was over, you had to do a clean installation.
Often, that meant you had to run down the earlier copy of Windows to validate you qualified for the upgrade price, and then, as with every new machine, run down every disk related to a program you used.
As a result, even at Microsoft, testers had two machines -- one running the beta, which they rarely if ever touched, and one they actually did work on. So, while Microsoft thought it had a legion of folks, both internal and external, testing the product, there were only a few of us -- I was typically one -- running the product in actual production. When we few complained about a problem, our voice was lost among the masses of folks who seemed to be testing the product but rarely touched it.

Windows 10 Fixed Both

Migrations started to get a lot better with Windows 7, but they are brilliant with Windows 10. You basically log in with your Microsoft -- or if you're on a work PC, your work ID -- and all of your settings, apps and personalities transfer down from the server (be aware that this doesn't apply to legacy apps or if you are coming from Windows XP).
Once on Windows 10, getting one, two or six PCs is login-easy, and as you move to the newer apps, the experience is similar to what you currently get with iOS or Android. You buy a new PC, log in, and after a short wait, your new PC looks like your old one.
The even bigger move, at least when it comes to creating a reliable product, is that those of us testing Windows 10 automatically will get upgraded to the final version with Windows Update. Since we started with a valid version of Windows 7 or 8, we still get a free upgrade to Windows 10 without having to figure out what happened to our old Windows disks.
This means more of us actually are using Windows 10 in production, and that the number of testers Microsoft thinks it has internally and externally is one hell of a lot closer to the number it actually does have. I do think it is likely going to take a while for some people to break a decades-old habit of using two machines, but it is still a huge step in the right direction.

Wrapping Up

Just like the testers, I too am going to now have to break a decades-old habit of whining about the upgrade and new hardware process for Windows. There are a lot of new features in the offering that fix issues with Windows 8 -- like Continuum, which morphs the product between tablet and PC mode.
However, the one that I think is the most powerful, because it fixes a problem that is decades old, is the feature that lets you almost painlessly migrate from an old to a new PC. That's something that should have been fixed in the first version of the product but actually did get fixed in this one.

We all have a lot of regrets. I have two with regard to Microsoft: One is not going on an interview there in the late 70s; the other is turning down a tour of Bill Gates' house. He'd offered to take me, but I'd thrown out my back and was in massive pain and felt I needed to address that first.
In hindsight, I should have sucked it up. Even though I was given a rain check, I was never able to call it in. The part of the house I really wanted to see was the home automation component, particularly with regard to entertainment.
Gates had a unique system. The pictures on the walls were flat-panel displays, and music changed automatically with the pictures, according to the tastes of the person viewing them. You wore a badge that told the system who you were, and it knew your preferences. I always thought it would be really cool to have something like that.
Well, a startup called "Artkick" has launched a crowdfunding project on Kickstarter for Look-- a next-generation large form digital picture frame (up to 40 inches) that can bring you art personalized to taste, and take feeds from your -- or anyone else's -- social network account.
It doesn't yet change based on who is viewing it, and there is no music aspect, but those could be future features -- and given the cost is in the display, likely not very expensive ones to add.
I'm thinking that if you had a lot of kids who were away, rather than mounting a large picture of each child on the wall, you might enjoy a dynamic digital picture frame showing what they're posting on their social network. That would let you feel like you were in touch with them -- or perhaps occasionally have the crap scared out of you (kids can do some crazy things).
