The e200 series lcd's are air soldered onto the board. If you don't know what that means then your not going to be able to swap the screen unless you invest 300 bucks or more in a hot air soldering set up. The memory is the only electronic pat that is easily swappable. The board is 99% surface mount parts so while you can with a steady hand and a good iron replace the headphone jack the majority of the parts are not user replaceable.
As to the comment that you wont buy or don't like this. This is exactly what the vast majority of consumers want. Cheap quality to get this you have to make these small with allot of power and functions. Either you make them expensive with easily replaceable parts or cheap with small inexpensive surface mount parts.
I have been repairing electronics's for a living for about 26 years now. When I started almost every part was made to be replaced. These days people want fast and powerful. The way to do that is to make throw away electronics. 20 years ago if your tv broke you brought it to me to get it fixed. These days when your tv breaks you chuck it run to wally world and buy a new one.
