The Unknown>Neo has been in the pod his entire life, yet when taken out, no operations or anything are done to his ligaments. It's pretty much impossible for him to have been able to walk after being taken out of the Matrix w/o surgery and rehabilitation.
true his body would be in a crap state and would need to be repaired. this is shown by him almost drowning and having to be carried after the claw picks him up. his rehabilitation is shown- such as the needles that presumably repair/strengthen his muscles.
also according to the two dates shown in the 'trace program' scenes at the start and end of the movie the events take place over 7 months. this would suggest that the majority of the seven months is spent with neo in his rehabilitation as the action takes part over a short period of time: a couple of days before he is freed, a short period of time for training etc, then the Oracle Visit till the end of the film which all happens across 1 day.
The Unknown>Morpheus says that he's been looking for Neo his entire life, but he got out of the Matrix probably as a teenager and wasn't allowed to be on a ship till about 17. So that means he's been looking for Neo for at least half his life.
technically you are right but i think 'all my life' can be a figure of speech and doesnt have to mean from the second you were born.
also as Morpheus spent some of his life plugged in to the matrix (unaware) he may not consider that as being alive or a true life. therefore he could mean that since he was freed and learnt about the matrix+war he has been searching for a person who can end them.
The Unknown>Link says that Neo's "doing his Superman thing", but Link is from Zion, not the Matrix, and though he may have been told about him, how does he know who Superman is?
i think you answered your own question there; 'he may have been told about it'. if you were born in zion you would naturally be curious about what life was like in the matrix.
also he is an operator so although he doesnt enter the matrix he views it on the ship.
