The screen is nice, full-HD resolution. The earlier models suffer from some ghosting, but it's very usable. The casing is very good and very strong, made with magnesium alloy (better than what I've seen on more pricey Thinkpad from the same era). The keyboard is good too. (I didn't liked the keyboard from the previous xx30 generation, I'm a classic-keyboard fan, but I must admit the keyboard is good on Yoga S1 and Yoga 12). The battery last the years. Nowadays, a used S1 would still have 80% battery capacity left. You can put an additional M.2 SATA SSD (size 2242) in the WWAN port. The tablet mode is nice, with the keyboard that retract itself when converting in tablet. (When it was released in 2014, there was lack of support for the tablet-mode and screen rotation under Linux, and users had to develop specific custom scripts. But now with the 18.04 version of Ubuntu and above it runs out of the box).
