There's some differences between X220 & X230 's keyboard:
X220's keys are closed together & surface is flat
X230's keys are 1-2mm apart & surfaces are curved
Any links or inputs from EE will be appreciated:
a) how's the keyboard's design better in X230
b) reliability (keys dont fall out easily) & durability (dust going into the keyboard)
c) sensitivity & bounciness/feel of the keys
Is the bundled X230's battery longer lasting than X220's ?
