The main reason i bought this phone is for the pure Android experience, no Samsung crap, no network software, just Android.
I don't even notice the Samsung crud on my SGS2. Using Go-launcher I just hide the apps. Samsung have made some handy additions to like colour presets, brightness from swiping nitificaton bar, great media support, gpu acceleration. Only problem is delayed updates. My battery life is great thanks to a great stock rom and exynos.
