> Considering that the x250 is pretty small, they have less displacement than other keyboards (coming from a T410)

The irony is that until the 40/50, X and T series had the same keyboards – an X201 and T400 used the same keyboard, as did the X220/T410/T420 and X230/T430. The form factor (which also didn't change from the X220/X230, i.e. same space available for the keyboard as on a T410) is not a justification for crippling the keyboard.

> There are minor changes in keyboard coming from the T series.

The new T series has almost the same layout, it merely retains the Insert key (while its usefulness for most users is debatable, Lenovo ties it to the Fn switch on the X250 – it's either End + ACPI hotkeys or Insert+Function keys, annoying).
