Pretty device, nice form factor and integration concept.
I would be interested as long as the battery life is comparable or better than other mobiles and the phone can make and receive calls with no problems which is why i am a huge Nokia fan. A phone that can't make or recieve a call with ease and little frustration will eventually become a paperweight.
I will give this new iphone 8 months of early adopter use before I would even think about shelling out for it. In other words let others go through the pain of firmware, reliability, quality and other various issues. They can work out the kinks and i know exactly what to expect and to avoid.
