The installation was problematic:

When you first install me the older driver of the network card (Intel 82579V, onboard) was marked as not compatible with Win8 and I was asked to remove it. As far as also understandable because Win8 would install a new driver.
Some other application programs were displayed for compatibility reasons as "check", and the Bluetooth stack.
The virus scanner (Norton 360) I've uninstalled before upgrading. He may be marked as compatible, but you never know where it engages during the upgrade ...

I have "maintained apps and personal data" option is selected and started the upgrade.
The installer launched extent flawlessly, but then hung at 90% installation progress. Have the computer then started again and initiated the new update.
Now the update ran on (not hung at 90%), but then came later in the message "unsuccessful installation, age status is restored" (or something similar).
This I have done a total of twice, but both times with the same result.
Now I wanted to Win7 the latest network card driver, which is also suitable for Win8 download. Just a pity that before the old driver had to be uninstalled. My Win7 thus had no Internet access. So download the appropriate drivers with another computer and install via USB stick.
However, this did not affect the upgrade, the driver had to be uninstalled during the upgrade again.
After several attempts and "googling" for clues (which did not lead to success for me) I have selected "Just keep personal data" option when upgrading now, lo and behold, the upgrade was now properly through.

Although I must now install all applications again, but there was no compatibility issues. All applications could be properly reinstalled.

As far as relating to installation.

Ease of use:

The home with the apps and tiles (or whatever you want to call this also) are nice to look at and for a normal user who wants to use the standard programs, certainly a nice touch. It's but deeper, so the normal desktop is the first choice, especially when PC without touchscreen.
Actually, everything is of the functions such as Control Panel, Computer Management etc. in external affairs remained the same, only now to get on a different way there.

That the Start menu is no longer available, due to a change in thinking, but ultimately you can do anything as before.

What is important for me on Windows 8, is managing corporate networks (domain membership, group policies, software distribution etc.). Since the (tiled) interface for me not playing first the "first violin".
The start behavior is better, the boot time (or rather of displaying the Windows logo to the application) has considerably shortened, which I noticed as the first pleasant.

The problems with the installation I do not see as a problem of the actual Windows 8, but more in the setup routines. It would have been nice to present the Abruchursachen a little more detail, instead of "Something went wrong ;-)"
to report.
The handling of the apps is certainly habituation thing, but when I look at z.Bsp. look at my Kindle or iPhone, the everything does not take much. In Windows 8, I can continue to work as before, have all integrated (yes, there are certainly third party tools which make certain tasks better and more easily) and can routine tasks prima scripts.

So for this reason I can not say yet whether Win8 a "good" operating system or not. It remains to be seen over time, if you open mind deals with the details. Contrary to many opinions Vista was now not "soooo" bad.

It applies the principle that "New systems generate new problems" and "New is not always better, but just different" ;-)

A star deduction gave it for problematic installation. Ultimately, however, comes down and I am satisfied so far for now.
Let's see how it goes.
