its better you go with xperia neo v or xperia pro.because neo v and xperia pro is more advance in performance like new gen processor, more ram, good touch screen in compare to this and also sony does not provide android ics update for this device.

ACTUALLY IN ALL RESPECT IT IS A BEAUTIFUL CRAFTED PHONE.
MOST USER FRIENDLY,STUNNING CAMERA,BRITER SCREEN,SUNLIGHT VISIABLITY AND STUNNING LOOK MADE THIS PHONE A BEAUTY.
SINCE PURCHASE I ENJOYED AND I WISH TO GIVE 10 OUT OF 10 FOR THIS PHONE

I Have been using the Xperia X10 for 6 months now, its a gr8 Phone, the software is fine, recently updated to Android 2.3.3. The only problem is the battery life, discharges very quickly. Speaker sound is not that gr8 either.

Guys ...which mobile you want to buy it's depend on your needs

if you like application : Go for I phone
if you like messengers : Blackberry is the one.
if you interested for videos,camera, voice Quality : Sony X10

Looks great, feels great, and the features are great!!
A beautifully crafted smartphone.
But the only thing which isn't great
Android 1.6!!!!!!!!

This is the best mobile in its class.
Those who have given negative review sure does not understand android os...
