I have the e635 and don't see anything that great about this phone. The reception isn't as good as my Motorola v300 because of the internal antenna - and the ringers are awful....I downloaded hifi ringers and they sound about 1/10th as good as they did on my v300.
It's small - and cute - but - it's just not that great.
Now I'm seriously thinking about the Moto V360!!! That looks to be a really good one too! I thought I liked the Samsungs...but...I sold my E315 and am now going to have to replace it either with the Nokia 6101 or the Moto V360.
