You are correct there is lag. I was playing Raiden and man it sucks controlling that thing with touch.

I think it's a lot like steering wheel feedback in a car. I absolutely loathe the new "electronic" steering in vehicles because it's removes any tactile feedback from the front wheels.

Most people couldn't care less. It's just a preference in what you are used to. I tolerate how Android works, but I still heavily prefer the immediate snap of IOS.

Yeah personal preference is perfectly fine, but to say thats how it should be for everyone is a different thing entirely.

Having used many devices from both camps, I find it odd that I don't recall any serious scrolling differences between the two? All I know is that both tend to choke when scrolling long lists.

I don't know.. I still hope more Note 2 users chime in to help the OP. I am curious to the extent how input lag is perceived in relation to touch sensitivity.

For example, My Nexus 7 is incredibly sensitive to touches. It almost feels as if it detects my fingers even before I touch, so I tend to be careful with it, and got a book cover for it. On the other hand, the touch sensor of N4 seems much duller and requires more pressure. It's not a matter of lag and probably not what the OP was talking about, it - touch sensitivity - did affect my perception of responsiveness at the beginning.

Note II is very sensitive, IME. Sometimes end up tapping twice without even really touching the screen. It's extremely noticeable if you have the touch sounds enabled.

Lol wow. MS's success in mobile has nothing to do with the current state of input lag and its future.

So why link a Microsoft video about how they think touch input should be when we are talking about how android does it?

If you enjoy input lag, I can't argue with that. I prefer that tech moves towards no input lag and the MS video is a good representation of what it would be like.

So tell me what advantage I'd see if my phone screen scrolled like it was glued to my finger?

Like we'll never need more that 512k ram?

The advantage is the advancement of touch. No input lag increases responsiveness and is one step closer to having the device be an extension of your body.

Going to have to agree. Things just feel so much better (touch wise) on WP and iOS. I still prefer Android at the moment, but it often feels like the thing is moving through molasses.

Each version of Android is getting better and better though. There is a noticeable difference between ICS and JB, and don't even get me started on pre-ICS...

So the OP hasn't returned and this thread has followed down to the path of usual horse bidding. Here is my contribution.

The iPhone is 4S. Don't have 5. Chrome on Nexus 4. Surely not a fair fight but I will let others draw their own conclusions.

What does the bold actually mean when you're talking about a phone?

While doing literature research for my thesis, I came upon a paper, that presented results for 3D gesture recognition, with a visual feedback.

They compared smoothed vs raw rendering of the visual feedback, and detection rates of the performed gestures.
They expected the raw data to permit the user to better control the movement, and perform cleaner, better to detect gestures. What happened, was that the smoothed visualization actually gave a positive feedback to the user, who then himself made smoother movements, which led to more accurate detection of the performed gesture.

It could be possible, that this effect is being exploited here.

I can't comment on the Note's performance here but I think people who assume human interaction with devices should be completely unaltered with no element of smoothing or correction are being incredibly naive. A big squishy finger making contact and gestures against a screen is not a scenario of exacting precision that people make it out to be. On my Nexus 7 you can clearly see there is an elasticity in the swiping. The initial pull causes a slight spring where the content catches up with your finger and then follows it directly.

Is it that hard for you to think outside the box? With no input lag or increased accuracy, the touch UI becomes more realistic. It feels like you're manipulating a real physical object.

A good example is writing on paper. With no input lag, touch can mimic that physical action.

Thinking even farther outside the box, you can imagine touch interfaces like minority report.

Overall, having input lag is a gap between you and the touch UI. Like a pencil is an extension of your body to paper, this can also be possible with touch.

Input lag has no place or use for touch and is not the intended effect.

Put a book on a table and push that book off. How long did it take for the book to change movement when you first touched it?

The initial delay/elasticity you speak of on your N7 does not exist in real life. If the book is in your hand as you move it, it cannot physically exist before your hand movement.

But you're not pushing a book, using a pencil, manipulating a real object or even a representation of a real object. You are not in minority report.

You are using a phone with a small screen. I don't want it to feel like the real world, it inst the real world. It should react according to its own rules.

the last thing I want is a skeuomorphic approach to touch input whereby we have to do it one way because that's what a book would do if you pushed it.

The initial delay/elasticity you speak of on your N7 does not exist in real life. If the book is in your hand as you move it, it cannot physically exist before your hand movement.
Any item being pushed along a surface will exhibit a non linear motion due to dynamic friction taking over from static friction. There will be an initial jolt and your hand would need to apply less force to keep it moving at the same speed. Which will never be applicable on a touchscreen until it can start pushing back on your finger.

A lot of swipe motions in touchscreen software mimics the turning of a book page. A book's page bows slightly as you begin to push before it flips over. Google currents even behaves differently depending on if you're going back a 'page' or forward. Android desktops moving clearly have a deliberate, non linear algorithm being applied. I'm petty sure these sorts of very minor UX decisions are backed by plenty of research into user preference. If it feels more pleasing to more people then that's what ends up being part of the device.
