I was iPhone 4 user for 2 years and I just bought Note II. The skinny screen simply unacceptable and dated to me.

Now I can view Instagram, movie etc very clear and more enjoy <--- the user experience and satisfaction iPhone(s) never able to bring me.

Plus, the battery is awesome.

I just compare my iPhone 4 and Noe II, comparatively,

iPhone 4 battery suck, I heard same with 5, but nvm, I can use powerbank.
Note II build not elegant and feel like cheap plastic, but nvm, I can choose elegant feel flip cover.

But I am not using a dumb phone, I am using a smart phone and espect my device to perform like a pocketable device yet give me clear view of picture, movie, document etc. Apple refuse to acknowledge the needs of a acceptable screen size and still maintain the skiny skin into year of 2013! With the leak of 5S/6 prototype, I see no near future of wider screen and opt to try Note II.

Unlike other shortcomings, screen size find no complement accessory and replacement is the only choice.

Yes, I spent thousand in apps and reluctant, but what to do with a 2010 screen size? I will living in 2013 soon.
Honestly speaking, no different to me on the smoothness of flip screen or lagness for the two devices I owned. And I choose a custom launcher I like and I feel the satisfaction. I don't jail break or root.

Yes, like Windows, as Android occupied almost the entire os usage, it attract malware and I need disciplne as to precaution and prevention.
