Dont get it, why make both? Why make the customer decide on such mundane criteria. Ridiculous.
It's smart, this way Samsung can appeal to those types and also people who just want a normal high-quality phone with no gimmicks at a more reasonable price.
He was convinced (via marketing) that this is the only phone with that ability.
My rooted S3 running on Beanstalk can do it.
What I'm trying to say is, yeah, gimmicks, but to the poorly-educated consumer.
I personally find the edge to be just another thing that can go wrong when I drop the phone.
Price the S6 more reasonably and place the S6 Edge to capture the higher end market where their premium brand is more valuable.
