Fran, it's well known that there ARE considerable hardware differences between a G70 and an E80.

There are quite a few features from the E80 that Roland explained (a long time ago) could NEVER make it to the G70 because of the hardware. The lyrics viewer in style mode, the .bmp viewer, amongst others. Remember there are TWO Mastering Tools sections in an E80 (one for the Keyboard Parts, one for the Style/Song Parts), two extra MFX sections and a different output structure.

The E80 is anything but a repackaged G70...
