Question [Q] Opinions for a concept phone project - please have a look!

I am planning on designing a concept phone for a project.
I wanted to here some opinions on what people like and hate.

Here are some guide questions that you can think about and post - you don't have to answer these exact questions they are just a guide:

What do you look for in a smartphone?
What key aspects are you attracted to with a spartphone?
What shapes and colours do you like your smartphone?
What features do you look for in a smartphone?
Do you like hard or soft touch buttons?
Power button on top or on the side?
What is the maximum price you would be willing to pay?
What do you dislike about your smartphone?
What do you like about your smartphone?

And add anything else you can think of - what do you like and hate?

Thanks a lot for your help and opinions
