Anyone made the move from a Slim to and OLED and wish they hadn't? Still got my Slim and play it occasionally but always hearing about how much people love the OLED version. If it's been a good move for most I might look at selling my Slim and trying to get hold of an OLED cheap.
Why in the world would you give up all the Slim's benefits just for the one benefit of the Phat? No way. I could never go back. That one benefit btw, is really questionable at best. Oversaturated colors and the Mura blotches which get worse over time. (There was a thread on GAF about this once.)
Aside from that, it's been what, almost 6 years since phat launched? The batteries are getting old, the screens are getting old. The OLED tech in Vita at the time was pretty young. For reference it wasn't until 2016 that LG started promising 100k hours lifespan for their OLED. Back in 2011 you're probably looking at 20-30k hours at best, maybe even less! And in that time the further along it gets the more the screens color luminance fades.
Like I said, would never go back. NEVAH. :p
