For me is GS2
Seriously iPhone 4S is a joke la. It's all old technology
re-packaged as new.
Siri is also no big deal. Maybe it will provide 5 mins of
entertainment and that's it. Do you seriously want to talk to your
phone in public?
Btw if you really must have Siri, Android now have it's own
version called Iris which you can download for free from Android
Mkt. Just also for yr ref the developers of Iris wrote the app in 8
hrs 
Oh ya I also hate the fact that iPhone layout is not
customizable.
Anyway I think that if you an easy to use smartphone which you
do not need to customize much than get the iPhone.
For your info, before Siri was around for many months ago, Android
already have something similar and it's called Vlingo or something
like that. BUT Apple did their marketing better, and with a cheer
group of fanboys, Siri became their key feature... imagine this
feature already available in other platforms long time and now they
market this as their key feature... Also touch screen phones or
tablets already available in market long time ago even before
iPhone or iPad was in the market, but once again, Apple marketing
powers can persuade anyone to get their products... they can even
sell iShit to their fanboys for $300 and they will buy... they
might complain it's shitty but they will still buy... what i didn't
like about steve jobs is that apple copied other people products
and they find it ok, but when android came out, they say it copied
iphones... wah lao... say one thing but do another... and also
steve jobs cheat his best friend's money, what kind of person will
do that... your best friend leh... over a few thousand dollars...
also jobs had a daughter and never acknowledge her, and leave her
daughter and the poor mum to live on welfare for years... bet you
guys didn't know all these...
