Corrected entry: When Chuck sees the Intersect images for the first time, it takes hours for him to see them all (as the scene stretches from the end of the party to the next morning when his alarm beeps for work). Throughout the series, many other characters upload the intersect and yet for them it never takes more than about a minute to see all the images.

Correction: In the first episode Chuck is receiving the intersect as an email attachment on his computer. All other instances of an intersect being downloaded involve specialised devices, multiple screens, high-tech glasses or whole rooms or are updated forms of the intersect.
