The pager ('less') in a console is not a good solution for everone:
  - People used to GUI editors (kate, nedit, ...) miss a scroll bar for
    navigation. You can't use kate or nedit as a pager.
  - PAGER="vi -" also reads all input before it displays anything.
  - PAGER="xless" likewise.
  - In Emacs shell-mode, with PAGER="", you see the output as it is produced,
    but it's disturbing to work in a buffer which is growing, where the scrollbar
    continues to change its position.

It's OK for many people, but not for everyone.
