remember the gameboy colour? well if you every owned one you'll know that, yes you can see the screen wen their is ample light. you'll also know that the screen always looks ****, colours are always bland, contrast sucks beyong beleif, and you cant use it in the dark, or even slightly dark.
now you say your a traveller, you should be able to use this in airports, they have good lighting, it'll suck but it'll work. If your flying at night, dark sky, you will find it VERY difficult to see your screen, if you can at all.
i mean look you dont really have a choice anyway and the chances of the backlight dieing really i doubt are very high, if it does you'll survive, neway good luck till march.
