i saw above some people doubt it's function, i dont. i work in graphic industry and am often wresteling with the quik-key-combinations of every program (diffirent in every singel program) so by showing an icon on a cirtain key really helps.

it's indeed useless for gaming since thats all about feel, ou dont have time to watch your keyboard for wich key to press. but for aplications it's a whole in the market atm. im looking forward to the time this is mainstream.
