Of course I see the QB. as a full-blown musical instrument. Even though I have a Ph.D. in music, I have no talent as a piano keyboard player. Others might see it as a musical toy or gadget. I alone, after fifty years, think of the QB as the UBER MUSIC KEYBOARD FOR THE 21ST CENTURY.
My ultimate ambition is to see a QB in every crib and knapsack in the world. Not to mention, every concert hall.
