What's your opinion about touchwiz ?
I like touchwiz for functionality but don't like design of it.
Its ugly
I think Touchwiz performs very excellent but feels slow because of bad frame rates but in reality its
same speed as stock Android.
I like so many options they give under settings for every app and also settings etc.
For example , Many browsers offer reading mode and leave it like that but Samsung's browser gives option of night mode inside reader which is pretty nice during night time usage.
I have used tonnes of gallery apps but none of them given option to have background music while slideshow but Touchwiz does (only other devices I see are iOS devices for which that feature was added recently)
Music Player shows embedded lyrics (i.e lyrics which are pasted into original music file itself so that Its offline)
I generally prefer iOS for having all basic functions but Touchwiz takes those basics to another level by adding even better options.
Those small things add up to a very nice user experience to me.
When I started using Android 5 months back , I used Chrome , Quickpic , Alarm Clock etc. so many 3rd party apps but now I am using almost every Samsung app (except S-voice) because 3rd party apps all lack basics at one place or other.Those 3rd party apps are pain to use as well because of design inconsistencies.
One app has x features but misses y feature , other app has both x and y features but no z feature etc.
Only thing I am waiting for is aesthetic redesign of Touchwiz.Apart from that , I have no complains.
Hardware also , Samsung gets it "RIGHT".
When I say about SD-slot and removable battery , people say that SD-slot is waste and Cloud is a way to go but when I say that Samsung also gave me 50GB dropbox for cloud , they go speechless

There is Galaxy S2 in home which needs battery replacement because it got exhausted but still good for typical day's usage , do you know replacement cost ? $12 yep that's right official Samsung battery.
Do you know how much they asked for my iPod Touch battery replacement ? over $100 + 14 working days time (after shipping charges)
That's why those basic hardware things are important
for me.
As long as they make feather weight devices and thin , I am not bothered with plastic.
