Here is a comparison chart that I give my classes when showing them the difference between developing for the internet and mobile web. I will be showing this chart this year at AECT during my presentation on mobile learning:
•Many columns/tables->1 Column
•Defined Width->% Width
•High speed->3G/4G
–Data Usage problems
•Large Screens->small screens
•Keyboard->touch screen/small keyboard
•Html->wml | html/flash->html/html5/c++/Java
•Very compatible ->Device type (unless html)
•Plug ins->limited
Please see my video which discusses these in more detail: https://raypastore.com/wordpress/2012/04/mobile-website-design-guidelines/
