The IdeaPad and Yoga have poor, uncomfortable, completely flat keyboards with tiny useless arrow keys, low travel noisy keys without adequate dampening (equally bad as a £1500+ Dell XPS 15 9570) that are unsuitable for people who write more than 1 hour a day due to a punishing feel on your fingers and joints.
One positive aspect of the cheap Lenovo laptops are the normal Ctrl+FN key positions.
I welcome the use of the ThinkPad keyboards without unnecessary numberpads and was hoping for XPS 15 2018 performance and efficiency, but once soneone else managed to copy ThinkPad keyboards, there's nothing that differenciates Lenovo.
Keyboards are a personal thing, but ever since I started using the superb ThinkPad T470s keyboard, all other laptop keyboards feel like a disgrace - even the Dell Latitude 7490 only feels "good".
