Everybody seems to be saying basically the same things about Windows 8. It is really not a bad operating system-better in some ways than Windows 7. It has somewhat better security, native USB 3 support, can be installed faster, has good backup, starts up quickly, etc.
The really bad thing is the silly UI. The way it is set up it is like somebody at Microsoft who apparently has a distorted image of the world figures everybody very soon is going to a touch screen tablet computer. Even if every single ordinary person does that (not likely) businesses will typically still want a desktop UI. Somebody who has too much power and apparently not enough common sense at Microsoft needs to get a clue. No matter what happens in the future, and even if tablet computers do become the number one computer in the world, there will be desktop computers far into the future. The sad thing is that Microsoft really could have leaped ahead of Apple with Windows 8 if they had just made it possible for Windows 8 to be set up for whatever device it was going to be on-cellphone, tablet computer, laptop computer or desktop. Go to Infoworld and look up 'Windows Red.'
At the Windows Supersite it is explained how to set up Windows 8.1 so that a person can use the desktop better. Otherwise, there is various software that can be used.
If Windows 8.1 is set up so that it is better suited for a desktop computer I really have no problem with it. But there are other potential issues such as if Microsoft tries to lock customers in to the Windows Store, etc. Apple already kind of does that but I think Apple is better in its execution of the Apple App Store.
There are things to be concerned about in the future that go way beyond Windows 8 (8.1). Microsoft could go to some goofy subscription service where you basically rent Microsoft software such as Office 365. Right now they have said they are not going to do that. But Adobe has already done that with the Creative Cloud software.
Subscription services may be better for security but they also lock out independent developers, unless those developers sell their software through the Apple App Store or the Windows Store. And I don't know if security really is improved that much because according to what I have heard the Adobe Creative Cloud has already been cracked and pirate copies are apparently available.
