How and what would be important to your design?
Personally I would have below;
Hardware of Nexus 6P or Galaxy S7 with 5000mah battery
Running IOS
Height and width similar to Moto X Style with depth of iPhone 6S
Camera of Xperia Z5 or S7
Full customisation of material, colour and design similar to Motomaker.
Yes I would choose IOS at this present moment. Android can be good but sometimes tedious to manually change everything one by one. I would like a simple clean design which takes the least amount of effort for setup.
That's my frankenstein, what would yours look like?
I prefer the design of the maxwell smart phone. Pure simplicity of design and ease of operation, best of all its wearable
