- It does everything the function keys do (volume, brightness) but more. It lets you turn the volume/brightness key into a slider, or you can flick it left and right to quickly adjust. - Replaces otherwise mostly unused row of F-keys. Let's be honest, most people never used these (at best 1-2 of the F keys). - You can add your own buttons for quick actions - Context sensitive touch controls based on app. Few apps support it but it's only a plus here. - Escape key has a bigger hit box now. Granted it no longer has "physical feedback", but as someone who codes day and night on it I can assure you that you will get used to it if you simply keep an open mind. People just hate on it as they always do with new things they are not used to. Change always comes with resistance.
