Already owning a Sony PRS-505 I was excited to read about the new PRS-600. The ability to annotate along with an integrated dictionary (which were sorely missing on the 505) led me to purchase the PRS-600.
My initial joy soon turned to frustration though as the integration of a touch-screen on the 600 has introduced an unacceptable amount of glare/reflection. In most conditions I find I am constantly adjusting the position of the 600 to get a comfortable viewing position.
The new features are great and owners of existing models will feel at home. But for me, the clarity of the screen just is nowhere near as good as that on the 505 and for that reason.... I'm out.
