Just got my skinny pink vita in. Initial impressions are strange. I've only dinked around the menus for a couple minutes but it's enough for some initial impressions I think. First the elephant in the room, the screen.
Its a double edged sword. I wasn't expecting the black level to be as bright as it is, on the other hand all the other problems are completely resolved. Despite lacking the insane contrast ratio, the lcd panel is shockingly crisp and surprisingly warm in its color reproduction. With all signs of mura, weird vertical lines, and sub pixel grain far removed it is overall much more accurate and clean in its presentation. What it lacks in contrast it makes up for in clarity. The initial impressions of veiwing it at a glance are unfavorable but I think once I get used to it I could easily see myself not missing the 1000 at all. Most of the initial shock at the contrast on my part was due to the default brightness being cranked way too high. On the plus side the screen can be dimmed much further than the OG vita which will make it more appropriate for late night gaming sessions.
I honestly hesitate to call it a downgrade necessarily. There's definitely some drawbacks but it's really more of a side grade if anything. Also it's a big relief to not have to worry about oled burn in on this thing.
Other notes:
While it doesn't seem like it in pictures the trimmed thickness and slightly wider body make this much, much more comfortable to hold.
The buttons all feel so much better. The 1000 model always felt a little to tight in its button presses for my taste. They still depress quickly and with a notable click but they're easier to depress. This same notion applies to both the PS button and the start and select buttons which sport a much improved shape and are infinitely easier to select. Triggers have also been improved dramatically. They feel much snappier and I don't even have to loosen a screw on the back!
I can't tell exactly how but I think the wider body and improved ergonomics help better place the speakers between the thumb and forefinger rather than directly beneath the thumb.
I can't speak to the functionality of the smaller rear touch pad but the extra finger room is a welcome addition.
The stupid fucking PS button no longer glows, PRAISE BE TO CTHULHU!
Overall it feels a lot like the time I first picked up a DSi. Its just overall very, very nice.
