I think the notches where the silver screws are shouldnt be notches... they should be closed holes. The plastic is a little flimbsy and thats the reason it is falling apart.
I do not like the layout of the front. The sensor should be at the bottom in the middle. I am sure they tried... it may be too big to fit there.
The screen is in no way centered on the assembly. I am interested to see what it looks like installed. I am super super anal about little things like this and if its not centered it would bother the crap out of me.
