i dont know what version of the operating system the G70 had. All i can tell you is that i have been looking for an upgrade from the yamaha that i have (PSR8000) and have been looking for more tha 2 years. I have spent a great deal of time with the tyros and maybe 2 hours on the PA1X and 1 hour on the G70 (because the board disappointed me so much ) I can honestly say that the PA1X blew me away but so did the price! i will buy one when the price has come down. The tyros is nice and i was tempted but the G70 just sounded poor in comparrisson witn the former two. The demos on the net are great but all i can reiterate is that Roland have shipped a product out before it was really ready to be released. No matter what razzamataz they have tried with the promotion and trhe net preview the end product in terms of what i have sampled soi far is not much different in tonality to the VA series.
