No, after considering alot, I wiill not give up my original idea - the first project, and I call it the first one, will be screenless. Reasons? Simpler to design (schematics wise and all other ways one could think of), cost effective and thats it. Im not super genius to figure all out at the first time round now, am i? Lets face it, designing a board to do all the cellular stuff is going to be a harsh and tons of work for my first project anyway, especially since im quite new to it, and just starting to learn it. Easier to program etc. I will say this though: if I will be successful with this one, I will do another similar project.
Therefore, I bring to you a new, final model I have in mind:
Middle frame is metal, its just in the middle (kind of like apples iphone 4), but the deal here is, its magnetic, strong magnets hold it still, therefore no screws or sim slots is present to user, one simply removes it to access screws for disassemble or insert sim, change battery maybe also.
Front is polycarbonate, but it has this soft kind of coating on it, giving it sort of rubbery feel, you know, like the Thinkpads used to have.
Buttons themselves contain of two materials, glass and same soft plastic.
It has motor to put it in vibrating mode (holding down 9 key, you know its on when it vibrates, off when it makes a tiny beep). Some keys also double as +/#/* keys, not all is figured out yet.
Oh and it has wireless charging build in, just to remove any ports (since it will be designed to be water and dustproof)
And thats all there is as of now, new ideas/implementations still welcome
