Touch Screen...no tactile feedback...many people don't like to use them...including me.

The weight seems to be the biggest issue...the OS can be fathomed with patience (and hopefully, more updates)...but, since both Yamaha and Korg can make lighter instruments with neither loss of quality or durability, there is NO excuse for the excess poundage of the G70 (and E-80).

I didn't like the G-70's keybed, but then again, I don't like semi-weighted actions, nor do I like aftertouch...give me a light action, like the PSR, or weighted hammer.

It sold very poorly in my area, mainly due to lack of promotion and no regional clinicians.
