Reviews Word on the street

Galaxy S III  vs iPhone 5 

While the 3.5" display on prior iPhones seemed downright old fashioned in terms of screen real estate, the 4", 1136 x 640 display feels like there's room to spread out and read web pages without chronic zooming.
iPhone 5

When you combine the screen's vividness with the great contrast (black color that is completely black, not just very dark gray, as in LCD displays), multimedia consumption does get much more enjoyable, compared to the LCD experience.
Galaxy S III

Google also wanted to get in on the act, enabling you to rent movies at a slightly high price from Play Movies - and the selection isn't brilliant either.

Great point Mark, definitely a key consideration. It's pretty crazy how quickly it can cost to fix up a broken phone.
One other thing to consider is replacement costs of things like glass, cords, device plugs etc. I had to replace the glass on my phone and it cost me about $60.00 A friend had to do the same with his SIII, and it cost him $350.00+ All you have to do is drop your phone once... Cords, chargers and plugs are also a consideration. These add-ons will wear down over time and you might have to replace them. Consider the total cost of ownership, and realize that after a couple of years, your phone will be out of date. The availability of replacement parts is important if you want to save money.
Hey there, good suggestion. This is actually the North American, dual core version. You can see the International, quad core version, which notes the FM radio here: (you can switch between versions underneath the phone picture at the top of the individual product page, but maybe we could make this a little bit more accessible).
The international version of the Samsung Galaxy S III have FM Radio. Also consider posting the model of the tested phone, just a suggestion.
