I have the Samsung Galaxy S3 is now excited in use and am every day since about 2 weeks !!
After a HTC One V, I am now switched to the S3 and did not regret the exchange day.
The performance of the S3 (speed and "crash rate") are more a viiieelfaches. My HTC has ever suspended - this is me not once happened previously when S3 and I call it pretty :)
The white desgin makes absolutely my taste - I would, however, at an early stage to screen protectors access (eg by Mumbi), as the display but is a little susceptible to scratching (but still 1000 times better than the HTC One V !!)
All in all I am happy about the extent - as is to be a smart phone! Handling is very intuitive and well thought out from Samsung!
The only shortcoming: the display is a bit too big for my hands, so I often with two hands must operate - but there are worse ...
