i whored out and got one last nite as soon as i saw them all in the open at Best Buy. it comes with a voucher for echochrome as well, so that sold me.
The screen is really nice, and yes noticeable - i checked out Loco-Roco and Patapon to see the colors, no ghosting either so i tried out some 60fps games (gorgeous). the blacks look really nice, and colors on menus stand out vibrant. the whole screen looks more rich like a CRT. I donno' what else they could do besides letting us access the highest brightness (looks very nice with the contrast) without plugging the thing in. I haven't tried it out in the sunlight.
Monster Hunter looks fantastic on it, i didn't know they were using so many colors. I can actually see the red hands on a pissed-off tigrex now from any position.
the silver is matte/spray paint like any GBA SP and not the glitter boat-paint speckle ... which i didn't mind so much as the 2000 being too glossy plastic feeling. no fingerprints anymore
everything else seems to be in working order, haven't tried out the mic since i donno' what uses it. and yes, i feel like a slut but no ghosting should've been mandatory on the PSP from day one.
