I’m always the annoying guy praising how good the Vita is.
One of my favorite thing about it is how repairable it is! The screws are even color-coded! Changing anything is ridiculously easy. (Changing the screen is a bit harder but you can change the whole front shell which includes the screen very easily)
Direct message, I think it mainly comes from twitter where you could add a “d” before someone’s @ to message them, maybe the use of “direct” instead of “private” was to avoir the confusion with private accounts?
