the simple and honest answer to DNJ original question "does anybody need the T2) is no. neither do they need the psr3000. But these instruments and their features are nice to use. I would bet my PA1X that none of the pro musicians here can demonstrate that their latest trade up keyboard actually made any difference to their earnings capacity as musicians/musical entertainers. ( i must warn you that i welch on bets i lose !! )
Its just personal tastes and preferences that make us choose one instrument over another.
