As the review outlines the good stuff, I will focus on the negative just to support new customers to make a more informed choice. Unfortunately Lenovo did not improve on any flaw of the first ThinkPad Yoga 12, and even more - it seems they made it worse.
Screen. New TPY 14 has a HUGE bezel just as TPY 12. So it is actually a 14inch screen in a close to 15inch box dimensions. Of course we can live with that, but I would prefer the opposite ;-) I have measured that original TPY 12 would exactly fit a 14inch screen if the bezel was not like almost a full inch. Also the brightness of 300nits is actually a downgrade of the TPY 12's 400nits. And generally the screen specs are far from the best coming from the competition.
Heat. Original TPY "lap"top is practically unusable on the lap - the heat pumping exactly at the middle of the rear side even on normal load (like watching a video) soon makes it very uncomfortable. It seems now that 54C measured for TPY 14 is even more than TPY's ~50C. So if you will use it only on a desk, or you are OK frying your private parts - please.
Connectivity. In this department at least we see a full HDMI vs. the most exotic miniHDMI on the TPY 12. Everyone can decide on his own if interfaces provided are enough; however I would suggest to wait for at least one review confirming trouble-free operation of TPY 14 with OneLink Dock. There is a huge thread on that on Lenovo support site; I personally settled with Toshiba Dynadock and just gave up on trying with OneLink.
