The e60 does display notation, chords and lyrics, just like its bigger brothers. That is very good!
Steve, if you are songwriting, don't discount the larger, 76 notes of the e60 keyboard, especially if you plan to play or record live. In step recording you might not need or use the extra notes, but in playing you will appreciate them. The e60 styles (and access to the other G/E styles) are the most LIVE sounding that I'm aware of. I do a little writing and find the Roland to be much more inspiring than the Yamahas. I can't speak for the Korg styles now, but when I owned one they were great, but very out-front styles as opposed to the more subtle Roland rhythms.
