Samsung Debuts the Galaxy Grand with 5-Inch Screen
Maybe not for the US :(
Some people appreciate real state in trade of resolution. Might not be the sharpest display but has enough room to do a lot of things with it.
According to the specs the phone mustn't be so expensive, so, many people in other markets where carrier subsidies are not good enough to allow common people to get a top of the line smart-phone but would make good use of a big screened device for his/her work would be interested on acquiring such device.
It wouldn't be too appealing to most people in the US though, because most users look for a good device to consume media.
