What is LINE?
Line is a messaging app where you can make free calls and texts. Its pretty big amongst the Japanese.
They've been advertising like crazy on tv and on the radio here in the US as well. I don't know anyone who uses it. Aren't calls and texts already free? It's the data that you're really paying for these days, most plans have unlimited talk and text now. I guess it's cool if you have an iPod Touch though. Makes no sense if you have a smartphone actually, because if you're not on wifi this app eats away at your data allowance.
In the states I'm guessing the target demo is 12-17 or hand-held gamers.
But what's their selling point? What's the advantage over other texting/calling through wifi apps that have been out for a long time now? I couldn't imagine a scenario where I would use a third party app to call or text on a smartphone, unless it's a second line for a different purpose.
