I have three servers, two workstations, a gaming rig, a media center, five laptops, three tablets, and three smartphones between me and my wife. Windows 10 runs comfortably on my gaming rig, my workstation, my Surface Pro 2, my work laptop, my wife's laptop and her workstation.. server 2012 on the servers.
I don't understand what problems everyone is having with Windows 10. It was a painless upgrade for me, except for my Surface which came with Windows 8, and crashed when I upgraded to 8.1, did a complete wipe using 8.0 and an upgrade to Windows 10.
I mean, seriously, Windows has been the same GUI overplayed MS-Dos since the 1990s...sure, there have been updates and features, but it all still works the same... I can open a command window, drop to Dos and do the same commands on Windows 10 that I used to do with Windows 3.1....
And it doesn't work well with Mobil computing? Let me tell you about my Surface Pro 2... It is quiet, it is a little chunkier than my iPad, but unlike my iPad mini, it has a keyboard/cover with a built in spare battery for longer runtime...with the solid state drives and aluminum housing efficiently reducing heat and waste, it runs for about ten hours.
Seriously...if your computer keeps crashing on Windows ten, then either it is the computer that has the issue, or it is just not designed to run Windows Ten and you'll be looking to scrap it. I have one PC still running Windows 7 because it is easier to run old school games like Diablo 2 on it... Other than that, it'll be recycled by next year.
Don't bemoan your inability to run Windows Ten on a PC that you prefer Seven or even XP on...if it works for you, great. Maybe install Linux on it and play around with Ubuntu and Fedora. But whining that "Windows 10 sucks" because you can't run it is as pointless as wishing you could run Apple's cannibalized BSD Linux OSX on your PC... If you really want to that badly, buy a Macintosh Mini.. They cost about the same as a PC anyways, and everyone should have at least one Mac in their Household anyways if you have a student in school.
As far as this "Forcing 10 on to the public" debate that I have seen going on for months... I don't buy it. I have a catalog of every OS on disk from MS-DOS 5/Windows 3.0 to Windows 10. I can always run a virtual appliance of Windows 98 on my PC, or 2000, or XP.. Etc. progress happens because someone made it happen whether you wanted to or not... Either you roll with it or you miss the bus and make other plans.
Computers stop being useful when they no longer work the way they are designed to, not because they don't do the way you think they should...if you think your design is better, then build it yourself.
That is my view from the bridge...
