Sheet music evolved when it would be difficult to produce a different representation for each instrument. Now this can be automated it makes a lot of sense to produce specialised formats, such as tab for guitar or this for keyboard. As a novice keyboard player I'd certainly prefer to use this than sheet music. Having said that there are advantages in sheet music that a professional musician would find lacking here. There's no rhythmic grouping (the beams provide this cue) and I'm sure there are many others that I'm unaware of.
