I'm not really sure why anyone is finding this hard to follow. I don't see where I was being controversial.
Robbo, you seem to be a bit more with it than the average punter, why do people get so tetchy over this stuff?
People tend to get a little bit edgy when a person lays some praise on Apple, I'm not sure why, I find it easier to just appreciate both sets of hardware/software and buy what I fancy.
General opinion is that iOS is smoother and definitely more refined than Android in general. However the difference in smoothness between the Galaxy S III and iPhone 4S for example would be very, very small and could tip either way depending on what you are doing.
It's something that Google are obviously aware of, hence why Project Butter exists.
Apple are inevitably going to have an easier time with this stuff, as they make the hardware and the software all in-house, Google and Samsung/HTC/etc don't.
