I can attest, the keyboard on the 5th gen X1 Carbon is also excellent. Remarkably, they actually managed to improve on previous generations (which, for the record, have Backspace, Delete, PgUp, and PgDown keys) by increasing key travel. About its only fault is the Ctrl/Fn key position, but you can swap them via configuration for those who have trouble adapting. As an aside, I much prefer Fn key mappings for thing like media keys over dedicated buttons: fewer things that actuate means fewer things to break, fewer things that'll get crumbs or liquid under them, etc. The 5th gen carbon has one button aside from what's on the keyboard: the power button. The result is a much simpler, cleaner layout.
