Make it ‘easy’ to repair not imply that it is economic, since the signature indicates that the front glass, digitizer and LCD form a single component so that its cost is quite expensive.
The battery is also easily replaced by iFixit. An important because as you know, Apple punishes users and ensures revenue when using non-removable battery.

For customer service reparing MacBook Retina is so hectic and like a nightmare, well Apple has cared for his employee this time.
