What should I buy?

[2xmars11]

I want to buy a 10k phone......So What i want is>>>>>
A. Fast processing, no lag
B. Good touch sensitivity
C. Nice & a bit huge Display
D. camera whatever...doesn't matter
E. A nice pair of earphone
F. And 3G & WiFi

I dont know android or windows which 1 is good with 1Ghz Processor...

I Have chosen 4 options bcoz the budget is good for me......
Help!!!!!!!!!!!
1. Micromax A101 (I prefer mmxx but many guyz give bad comments...e.g., it hangs sumtimes, heats up when gaming or surfing net)
2. Samsung Galaxy Y Duos S6102
3. Sony Xperia E (Not Dual) (I doubt do jelly bean OS ll work well with 1Ghz?)
4. Nokia Lumia 510.

5. Nokia Lumia 520... the 510 has WP7 while the 520 has WP8.

The 520 has a better screen, better camera, 3G, wifi and will not slow down as u keep using it. And yes the Xperia E is a good option but install a few apps and even jelly bean will not help your slow phone.
