I wonder if it has next page / previous page buttons somewhere.
It has the other three from T2. And, because the touch screen is of an inductive type and requires a special stylus, it must have the page turning buttons?
Probably on the edges or on the back side somewhere?

Furthermore, it would be perfect for sheet music and could dominate the musician market, but it would be good if it had the next/previous page buttons as a double foot switch - possibly a wireless foot switch, but it should work with one device among many others in the orchestra.
Or a dedicated input, or through usb.
Sony would be stupid to miss that market.
I don't see any buttons on the sides or the back:
