Blotches are in games with dark areas constantly on the screen such as Thomas was Alone. I can live with it though, it's just slightly annoying.
You are right about the price comparison though...retina devices are 3x as much.
Did you recently get a Vita? I really only noticed them in the beginning and very rarely after that, like once a month I'll notice.... It has been a year, I'm not sure if the spots faded or I just notice them less.... I know what you mean, that second when you go from totally forgetting about them to remembering they exist is a bit of a let down. But as soon as an image appears, I'm happy again
Yeah mobile is pricey but people tend to forget that - due to the contracts sucking the cash a bit slowly, not all people here with Vitas will have them I don't think.
It sort of does a fair amount of what the phones do too, I was able to manage on a really terrible old nokia for a long time while I had my Vita hah.
--btw I was going through that "best communities thread" and saw quite a few VitaGAF mentions, which is pretty awesome.
