yes, exactly, i dun buy my device based on hardware alone but its features.  What the device can do, not what the device is made of.  Smoothness of UI is nothing if the device cannot help us much in daily life coz i dun just flip here flip there just to enjoy the smooth UI.

I want the convenience to write something down immediately during a call (or whenever) when there is no pen and paper around me.  I want the flexibility of multi-windows when i can do multiple tasks at the same time.  I want the screen to be bigger so that my aging eyes can see clearer.  I want to be able to install different custom ROM (with different themes and features) whenever i am bored with the existing one.

Yes, i do want the smoothness of UI but it is not my priority, as long as it is as smooth as my current Note II.   

Not to be brunt but the only nitpicking iPhone can do now is the "smoothness" of UI (if you insist) and the more content in their App Store/iTunes.  oh.. and also the many accessories available for Apple devices. 

Sorry, not a droidfrag, just stating the fact.  I just bought a MBA 2013 last month - enjoying the "smoothness UI" of MBA now. 

More RAM actually affected the overall smoothness.

S III lagging main issue due to it not enough RAM, and keep closing background task to let the phone still work in proper, and badly it can even close the main thing - touchwiz launcher.

When RAM is too little to handle everything, how you tweak also useless. Those custom ROM can run more proper as basically most is trim down the whole ROM thus less things run in background, this in-fact is not the real solution. If buy a phone, I want it fully utilize whatever given by the manufacturer, not a trim down edition.

Thus, adding more RAM in-fact is the better way.

Z1, Ultra Z, LG G2, all this flagship but its not the latest with 3GB RAM. Why? Samsung monopolize all 3GB in the market? 

Adding ram is just one of the way. Frankly i would say TW is not fully optimize for smoothness and having 3gb on Note 3 will not guarantee better user experience. That being said, TW got lots of really useful function to make it up.

it comes to a question, do we really need 3gb RAM? is it just a waste of resources? for user, having more is always good.. but for manufacturer, being smart, being conservative while it still can.. how if next flagship come with 5gb RAM, do we need that much? for me, 1gb RAM boooo.. but 3gb, i don't mind, because 2gb is still abundant…So far i never been in a situation that my 2gb RAM is fully utilized, so why 3gb? just for the sake of fancy spec sheet? its like a Proton Wira with big spoiler, does it really need that?   but anyway i'm dunno engineering stuffs, maybe the current/incoming Android needed 3gb RAM. or maybe TW is so heavy that it needed 3gb RAM while other UI running fine on 2gb..

As for iOS, that is different case, iOS is as dummy as it can for me, and nothing really real multi-tasking and no much background running task. So iOS no need high performance processor or a lot of RAM to utilize.

Actually example for myself, I know the smoothness always is Nexus series phone due to it pure Android.

But I never like Nexus, why? Simple, pure android features is really pure, quite empty actually as destEX said, Nexus phone never fulfill my needs.

I prefer more features phone.

the bolded part is not quite true. ANd there is more that goes into a good custom rom (keyword good) than just shaving things off. There is actual optimisations being done. the simplest one i can think of is partitioning more ram for the UI usage.

the program again, is not enough ram. Lets take Note 2 for example. 2GB.

Out of 2GBram, how much ram is being used by TW UI? not 2GB. a fraction of that. So how is increasing the pool of available ram to 3GB gonna change anything? Its got to go down to the TW UI framework itself. You dont need the extra 1GB to become 3GB to increase smoothness. WHat you need to do is allocate more of the 2GB pool into the TW UI for example, but even then, by right, u shouldnt need to do that because to do it means that the UI has memory leak in the first place. :/

when your S3 lags, the TW UI, go to your ram, and see where is the pool of ram being assigned to. Then you can get a better picture of why your device is lagging.

so yea. Optimisation is the keyword

the rest of your post is more or less spot on

thats the point.  do we really need 3gb?  i dont use all 2GB of ram on my htc one.

personally think that samsung needs it due to its features and smoothness

someone said that the TW can we tweak to get smoothness. 

that said, then my HTC one also can tweak to give even more smoothness.

We are holding computers, not phones anymore.  More RAM is ALWAYS a good thing to reduce paging. Why are in memory accelerators all the rage in enterprise database and application software??

More RAM lets you do more. Do not ever think you are using a phone to browse. It is a computer that uses your phone radio as a modem only.
