Saving material to flash memory is one matter. Being able to play a style from flash memory is another matter. Given that providing a keyboard with expanded memory or the ability to read from flash memory would cost practically nothing, it will be obvious that if the PSR2100 does not have this capability that it will be an purposeful impediment on the part of Yamaha to give people an incentive to buy their more expensive Tyros. That seems like a punishment to those who either don't have two and a half thousand dollars or who need onboard speakers.
