Well, the G70 has one or two (depending how you set it up) MFX insert effects units the E60 does not have, and a per-part 3-band parametric EQ that the E60 does not have (and styles edited for it), and in the past Roland have used noticeably lesser quality D/A's on lower line products (as do most manufacturers), so it's still hard to pin down the ROM size as the primary culprit in making the E60 not QUITE as good as a G70.

Who knows? Who cares?

It is STILL the only lightweight, 76 with speakers, and MOST of the good things about the G70. So, it hits a pretty well defined market spot.

Want to play a full 76 decent feeling keyboard, AND have speakers, AND not break your back moving it, AND have a few great sounding pianos?

It's basically the only game in town... 64MB of ROM or not...
