new Opus has 5 inch screen with 800x600 pixels resolution.

let's do a little bit of math here:
5 inch diagonal 800x600 screen makes classical pythagorian triangle 3,4,5
let's check it:
3^2 + 4^2 = 5^2
9 + 16 = 25

OK. we have established that 5 inch screen has dimensions exactly 3 x 4 inches.

Now, bear with me
800 pixels / 4 inches is ...
TADAAAAAA
200 pixels per inch. *Exactly* 200 pixels per inch.
i believe godzil was referring to the 6" screen. the 5" screen does indeed have 200ppi.
