I have played the G70 and as I said above I thought it was not worth the upgrade.
Yes it does have some good sounds and some decent styles, but when I thought of how easy the G1000 is to use and that it still sounds decent to say how old it is, the G70 didn't grab me by the balls (pardon the expression) in order to purchase one. The Tyros 2 did manage to grab me so that now sits above my G1000 and Korg Triton.
Each to their own
The demo by the way had a great Dixie style and was a good rendition, but the brass/trumpet sounds were very poor comparing them to the Tyros2.
