My friend and I just went to a store to check for Q10.
Just wanted to switch from Z10 to Q10.
After seeing Q10 with very poor quality of screen: not very clear, color turns to yellow, and not fine, as seen on Z10.
I am no longer want to buy Q10 any more.
After that, my friend bought an iPhone 5 instead of Q10.
I do not know why RIM select that type of screen for Q10?
