I have a 4th Gen iPod Touch running iOS 6 and I just wanted to say that it runs great
It stills runs almost every game fine (it plays Minecraft PE with Far render distance, smooth lighting, water animations, 3D clouds... without any frame drops, it plays dead space just fine [looks great too!], Real Racing 3, Mass Effect...) the only game that is bad is Modern Combat 3 which runs at ~15fps at a guess. Web browsing is very fluid (as fluid as my iPhone 5 when it was on iOS 6) as long as it is on mobile sites or basic desktop sites (in other words, not apple.com then
), can run all stock apps (apart from the App Store, it usually eats all the ram) at once without it force closing any of them or even stuttering between switching apps.
Maybe I am not finding the experience so bad as other users because I usually only have 3-4 apps open at a time but still. I know there are apps now that wont run/would crash on the 4th Gen iPod but to be honest, I haven't came across one that I wanted to use but couldn't because of crashing.
Anyway, just wanted to tell my side of things

And it is no where near as bad as iOS 5 on the original iPad.
