I've had very little time to demo the E-60, but what I've tried and seen I like very much. It is much simpler to operate than the g70. There are less styles, but the smart cards can hold infinite amount of styles and songs. There is no harmonizer, which is the only bummer about the E-60. The key feel is good, better than the Yamahas I've owned, but certainly not equal to the g70.
It is a pleasure to play. The styles are so symathetic to live playing and they sound so good. The speaker volume could be louder, but it is adequate for a small room. Except for a possible upgrade in this model, I don't think I'll be looking at/for anything else for some time.
Roland needs to promote the E's better. they are good keyboards but suffer from lack of exposure.
