Full marks for the laptop and a few useful tips ...

I have the Yoga 2 Pro with i5, because I want to lift no special applications with it and my old computer with its predecessor has been already more than adequate. The SSD is of course a piece of candy to the people like to say yes. As generally in Windows 8 computers Dinger start almost as fast as a Macbook Air. How long does it take until the OS zumüllt I do not know, however. My old computer was after 3 months still can get off to a flying start. But now to the yoga.

The keyboard is great. Slightly smaller than my Envy14 HP, but with an excellent pressure point for me. The denting the "SS" as its predecessor, it no longer exists as well. Absolutely great.

The screen is of course great. Since the films makes watching fun. Bottom left and right of the screen is slightly lighter, but you can see that only if you have a solid background and I noticed only by the home screens of some apps. I'm actually very picky, but that does not bother me.

The star deduction is not available for the laptop, but for the early stage of the market launch. The software needs to be adjusted a little until you can work properly across with QHD. But the basics (Office, Browser) work perfectly.

I can now express more positive about a lot, but a few suggestions to help you set up are certainly helpful. Because you have to tinker a lot until you can work reasonably with QHD resolution. Large icons on the desktop are there now really the easiest.

Scroll toward the touchpad: The scrolling is done by default "natively", ie when you pull down, then the image goes up. Who cares who should install the latest driver from the first yoga generation. There are as far as I can tell, no loss in terms of functionality and the handling. The driver then has the option to invert the scrolling direction. The driver from yoga 2 can not for some reason.

Chrome-resolution:
In order to work with the Chrome browser you are first in line for the address "chrome: // flags" field.
Then activate HiDPI Support,
Touch events and more active
Active streamlined interface for touchscreens.

WLAN problems: I had constantly disconnections. The problem was that ever the default gateway has been lost. Lenovo wanted to take back the device again because they have assumed an error map. Nonsense!
The router must first of all be operated with the latest firmware. That does not always happen automatically. In my router for Unitymedia which has already been enough and everything worked.
When routers of O2 was the router up to date, but even here he ever lost the default gateway (the router address, if you will). The problem was the WEP key. The notebook is understood not with this encryption. To avoid problems so best to use the same WPA2 encryption (How to do that in the best guide for the router read).

I for one do not regret the purchase after a few modifications and the Yoga'd bring 2 per repeatedly.
