Interesting though these teardowns are, they could be a bit more specific.
1. There are too many pictures in the beginning of the series just depicting the phone in different "poses".
2. I can't really see the point in the comparison of some parts of different models. Not many people have them all at home at the same time, and if they do, what are they suppose to do about it? If a part from one phone can directly be replaced by the same part in the other phone, then it's a different story and very relevant.
3. I would really like to see some red arrows pointing at what the text is referring to in each picture. Like if it says "Remove the seven screws holding the board", where exactly are these seven screws? Some of them may be hidden or otherwise difficult to notice. Same thing with the connectors.
4. If one owns such a phone, it would be nice to get all the pictures and helpful texts together in a pdf-file for future reference and repair.
On the other hand, the pictures are very sharp and well lit, so no complaints there. I would prefer "replacementprocedure" to "teardown", but maybe it's an unnecessarily long word. The only reason for anyone to look at these pictures, as far as I can see, is if someone is going to repair or replace a part on the phone (probably the screen in that case). I do a lot of partreplacements, that's why I look at these photoseries quite often, but as mentioned, they could be a bit more helpful.
