Sorry if this come as a post below my last post. Doing this on my Vita, cant copy and paste for an edit.
The white of the Vita is a more defined/crisper white than the iphone 4. Ive compared them both in sunlight. The White Vita is prettier, makes the screen really pop - i dont find it distracting at all. I was worried that it would be more of a detraction, but to me, its opposite. I own both and am regifting my launch black this holiday. He will be happy, sure.
2 things, most apparent (1 good, 1 bad) - the white disguises dirt and finger smudges, barely noticeable compared to the fingerprint magnet that is the black Vita. The black always looked dirty and smudgey all around.
The Blue PS buttton does shine through, near the left analog a little bit, at night. Not at all, whsn the room is lit. Never saw it on the blaxk. So theres that.
I wish there was a way to turn off the lighted button, having it only on for notifcations and such.
Overall, i love, love, love the white. Much more preferable than black. It looks more elegant and classy, too.
