yea, even meego is a good OS also
they ady have good sell with Nokia N9 dono y the choose 2 give up
nokia N9 have their own native code support, thus no need rely 100% on Java n app can run faster
the UI is also very good 

especially the lower front facing camera is the best
easy 2 use whn having face 2 face calling, if u keep ur eyes at the screen
it will not seem like u keep looking at lower place,

it is good tat xperia ZL have the front facing camera placed on lower part

lol actually xperia ZL impress me more 
ady got xperia P n xperia V at my home, using xperia S n nokia 920 as daily phone

i think i will pass tis both phone lar, just let them stay in my bro's company as a dev phone 

if compared to butterfly, i prefer butterfly's screen...

and i tot Z and TX have the same type of screen? why such big difference and obviously TX looks better from these pics
