I have the Lenovo Yoga 2 now for over a month. From the performance and the design I'm already excited about the first day. The processing is as it is written here often not all that great (slight creaking at the back) but this does not disturb / bothered me. From the software I am on the Lenovo own surface well used, with more setting options would be nice (maybe still is touched up with updates). Of the apps which all can be supplied easily uninstall or disable Security except HD, where you at least can eliminate the notification here. The battery life is not in practice 18 hours is enough for me but still good (come on 7-8 hours of constant subjection.
Now for the really worse Unfortunately small faults
For dark movie sequences or generally dark content, the brightness of the tablets is also darker which can not be switched off. After about a month I enteckte then a lack of has unfortunately decided to give the Tablet for repair. When the aluminum holding the tablet in landscape mode stand up and be the stand folds out lights on the left corner of the display a white "flash" on. On YouTube there is a review by this phenomenon can be seen clearly.
I hope that this defect affects only a few devices and I get my Lenovo soon again because it's a really good tablet (then there are also 5 star :)).
