Our company went with this exact model as the standard laptop last year.
Its too heavy, no Ethernet port even though its thicker than a t4x0 series laptop, all of which come with them standard and were our standard model for the last 10+ years.
Its docking stations are a joke and you need them to get wired Ethernet although the docking stations use USB NICs.
If you want to get access to the built-in PCIe Gigabit Ethernet, you have to get a proprietary dongle that uses their proprietary flimsy OneLink+ connector on the laptop end [you can see it on the side of the laptop in one of the pics].
Their docking stations use either USB 3 or the proprietary flimsy OneLink+ connector.
Battery is integrated and swapping anything out like RAM or the SSD requires taking the whole bottom plate off using 10+ screws and careful use of a black-stick which you will definitely do here as it only has one RAM slot and 4GB isnt enough.
Even though we will be rolling out Win10 soon, I dont see anyone using this with its flip screen as Windows is just cumbersome to use that way.
This year, they are going with its smaller sibling, the Yoga 360 which is lighter but still has all the same issues and they have dropped the OneLink+ connector in favor of a mini-RJ45 connection which still needs a proprietary dongle and docking stations are now using USB 3.1 only.
Oh, and their docking stations will not power the laptop so, while using them, you need two power adapters on the desk at the same time !!
It was'nt even on Lenovo's PSREF sheets for NA until sometime after it was announced to the rest of the world because the NA market is very picky and will trash anything that does'nt meet minimum tech common sense specs but somehow it made it.
