When synths came along in the 70's (yes I'm old) a lot of people said it would ruin music. It didn't. In fact it gave muso's more scope to be creative. As far as being bland and commercial, well, commercial music is bland and yes, it is a business as are the 'I wanna be a rockstar' TV shows but once in a while a real talent will come along that would probably never have been heard otherwise. Same goes for the 'entry level' (I hate that term BTW) instruments like the Di. Most kids or their parents can't afford the high end stuff and I must admit I would not be happy if I had forked out for a Fantom G8 just to discover my kids had lost interest after a couple of weeks. A Di on the other hand is more affordable and who knows, one of those kids might turn out to be the next Keith Emmerson (I hope you remember him)

.Roland should be applauded for making a great musical tool more accessible.
On the musical side of things, there will always be talented people writing great stuff even if it never makes the charts. Just look at the thousands of artists on the net giving their creations away for free. These are the real musicians.
Don't despair. The Di will not be the end of life on earth as we know it. The cream will always rise to the top.
As for the little gimmicks like the song player. I use an mp3 player through the audio input on the Juno G. It has a recording of our band minus the KBD parts and it is very handy for rehearsing or working out new chops. It's not just for wanna be's.
