This is already one of the most salient strengths and a major weakness of Yoga 3 touched upon: Slim, quiet and easy going at the expense of performance. The Core-M has enough power for basic applications, if you charged him with parallel tasks, but he works up a sweat and that makes, for example, in small jerks and increased operating temperature noticeable. Certainly not helpful are the background tasks that ensure the various preinstalled Lenovo utilities for utilization. Because uninstalling is advisable.
Otherwise, the Yoga 3 is well equipped. 4 gigabytes of RAM are enough for Windows 8.1 from the SSD is calculated not lush with 128 Gigagbyte, but offers enough space for the needful. Because the case is so nice and flat, the charging port is also a USB port from which the Yoga 3 has two more (2x USB 3.0). Add to that a multi-card reader.
The Full HD display is highly reflective, which is not a big problem when using indoors. On sunny days outside working but difficult. Touchpad and screen respond accurately to taps.
The battery creates during normal use (little video) almost 6 hours, but does not approach the well with a Core i5 including fan hardly makes noise on the term of the Macbook Air.
The silver Yoga 3 is trimmed for my taste towards pseudo-metal, which tarnishes the overall impression: It works by all the more like a plastic box. The model in Orange, I also had times in my hand, acts compared valent. The white yoga I can not yet assess.
Another point I draw from because of problems with the sound card, on account of which I have the Yoga 3 also returned. The built-in speakers have a very decent sound. If the severe distortion would not that affect both speakers and headphones the sound greatly. That seems to be a driver issue the Realtek sound card, but that neither could be clear a generic Windows driver by a driver update.
Conclusion: A beautiful part with teething and not enough oomph.
