Just ordered one from Lenovo in The Netherlands with specs exceeding the ones mentioned in the article. Lenovo Yoga Slim 7 14": 7840s, 32GB, 1TB SSD, OLED touch. At a relatively interesting pricepoint at EUR ~1400, incl. 5% discount for registering.
As benchmarks of 7840u/7840s notebooks (especially the latter of course) are rather scarce I'd have loved to see one of those tested properly...
