  - Make sure your TERM is exported appropriatly.
    Otherwise you may end up with less colors (M-x list-colors-display).
    Screen fiddles with TERM and emacs may end up supporting less colors.

  - Copy/Paste between regular X apps and the emacs will not work.
    You would need to use something like "xsel". See here [1]

  - Some of the keys may not work as expected. This will be 
    apparent especially when using orgmode. You may want to 
    remap them appropriately

  watch -n 1 ps -eo pid,ppid,wchan=WIDE-WCHAN-COLUMN,stat,command r

  > Not perfect, but I find it's more natural to write in org-mode
