Negative: A split system
Dissuasive, when a long-time Windows users for the first time the tile screen looks - and moreover with changing and flashing advertising in the individual tiles. Who understands his PC as a tool for professional and amateur, who will have to do nothing more urgent to switch off as soon as possible as this nonsense.
Also the update to Windows 8.1 will not change their attitude towards it. The objective, even users of older versions to inspire for the new operating system is still not reached after the update 8.1.
As a PC user, the tiles are not before you should be afraid, they are simply annoying, because they do not comply with the operation on the desktop.
In terms of usability, they represent even a step backwards compared to the desktop.
I am optimistic approached Windows 8, for example, to make friends with the tiles, I have not found app, I would really make use permanently. Ultimately, the tiles were just disabled, as probably many other people also.
The Apps are basically just scaled-down versions of desktop versions, but I need not.
Here's a balancing act between Maus-- and touch operation is now created and precisely this balancing act works annoying.
It annoys me, and then the time to deal with all the pitfalls and wiles.
What about:
Ubuntu and other Linux rescue systems that appreciates the Windows users, they are still usable in Windows 8 devices through Secure Boot only indirectly. Dual boot is difficult.
Establishment of local users is complicated by the ... do not want Microsoft, and directs in advance to the Microsoft account / with mandatory registration.
Skydrive is set up by default as a location for various processes. Whoever overlooks that stores its texts by mistake in the "Documents" folder of Skydrive account, and not in the local directory. Since then Microsoft know quickly who is among the critical elements.
TIP: Turn off When you first install Internet, then it will come to the local user.
For smartphones and tablets certainly a nice system, but because a PC is now time is always controlled with a mouse and keyboard, it is completely out of place here.
And it will be no matter how many updates can not change anything.
As a young child insists Microsoft on having still create a nice operating system. After the flop of Windows 8 and Windows 8.1, it is for Microsoft time, the mistakes.
