Android Phone around 15k

Hi,

I'm planning buy my first Android Phone...
I've used Nokia X3 for the the last 3 yrs and I think its time to say goodbye to my old Symbian S40 system (its still in solid/very good condition and not a single problem for the last 3yrs )


I've gone through the forum n other websites and zeroed on the following Model

Samsung Galaxy Advance [- Screen Size and Gingerbread]
LG Optimus L9 [-looks and not sure about build quality]
Sony Xperia L [-screen clarity...no Super AMOLED]
Samsung Grand Duos
(I'll not go 4 MMX, Lava, Karbon mobile...no to Lenovo also)

My Budget is around 15K...can stretch if its worth...
My Requirements are

1. Budget?15,000
2. Display type and size?4.0"+
3. Form Factor? bar
4. Preferred choice of brand? Samsung, Sony. LG, HTC
5. Preferred input method (QWERTY, touchscreen, numpad, touch-n-type).Full Touch
6. What camera option you want? Flash,Autofocus, Front Camera also
7. Preferred operating system? Android only...
8. Preferred connectivity options :2g,3g,wifi...good to have 4G
9. Preferred applications (Flash, Swype, GPS, etc)?Flash
10. Primary use of handset ? Mail,Browsing, Music, Video (TV Series)

I'm not a gamer but will watch HD videos (in Cab Pickup/drop time)...so good GPU won't hurt...Will play game occasionally.

I will user Mail Droid, Lync 2010 actively [office ] along with other apps.

Good to have good quality camera (anyway I'm also buying Canon SX260 also).

Please suggest
