Destructoid - We got our hands on a Vita running the newly announced manga/comic reading Reader software today at TGS.
The first thing I noticed is how great manga looks on the Vita's OLED screen. Colors seem to pop right off the screen and into your eyeballs, and black lines are sharp and defined. Color manga in particular is a treat. Every volume I flipped through was really easy on the eyes, and I had no problem seeing even the smallest detail.
