Inside tablet Goclever A103

Some time ago I bayed a new tabled. I looked for the cheapest one so I've chosen Goclever A103 which has Android 4.0.4. It's shown on the next picture:

The tablet is quite OK, especially if we consider that it was very cheap (bellow 200€). If we look inside it, we can see that there is no reason for tablet to be pricier. 

Silver plate is the screen. Smaller silver plate with the blue plastic is the battery. And the green thing is the "mother board". And that's mostly all. Oh on the left upper side is the webcam too.

On the left upper side you can see the A10 (Allwinner A10). This is system on chip (http://en.wikipedia.org/wiki/Allwinner_A1X) which is used is some other tablets. Same hardware, other brand can be seen here http://www.amazon.com/Android-Capacitive-Screen-Tablet-MID108W/dp/B008RF7LW0 .


Why are other tablets so pricier (Apple Ipad, Samsung Galaxy Tab)? I believe that hardware costs are similar. So somebody makes so much money.
