First off, its not made of normal plastic and second, pretty much everyone is praising the S3 for how fluid it is and you found lag and stutter? Sure you did, keep your iPhone please, thanks.
Look, I'm not here taking sides. I was open to switching. No need to start defending one over the othe. I'm just stating my experience. It's on par with other android devices I've tried in terms of fluidity but it's not at the iOS level yet. I clearly can't be the only one to think this since google themselves tout improved fluidity as a feature of Jelly bean. When I play around with a Jb device, I expect to have a very different experience. There's only so much a solid processor and lots of RAM can do when the operating system is not optimized.
Seriously, this automatic jump on mild criticisms is pure bull. I could come up with things about iOS that bother me but this is clearly not the post for it.
