- click on image to view full photo (about 1500x2000 px)
On macro photos are displays of FSC LOOX N560 (VGA screen, mine) and ASUS MyPal A636N (QVGA, friend's device). Both has 3.5" screen. Photos are different from the original in first post on this thread - I focus on standard text, images and icon. Not on extremely small text whis is not used by many people.
Just see, compare and make your own opinion which resolution is better. I won't use QVGA anymore.
