Thanks. I am not singling out the X5 for sunlight abuse. My Blackberries and iPhone 3GS were all nightmares in the sun. It is really only the new generation of expensive reflective AMOLED screens that deal with sun well and Fiio is not going to use those at the X5 price point. A matte screen protector might help a bit but the theme of the X5 is also very dark with grays and muted colors against black. It looks great and I wouldn't change that to get a bit of sunlight advantage. Just step into the shade. :-)
Maybe Fiio will give us a theming tool for the X5, and you could tame the problem a bit. I've had fun playing with X3 themes and did make it dark gray with flat elements instead of black with glossy elements.
