I change my prompt based on whether I am logged in under X or not:

         case $TERM in
         xterm)
                 # Cyan prompt, host, tty & date in xterm title (36 denotes cyan)
                 export PS1='\[\033]2;\H:\l (\d \t)\007\[\033[36m\]\h:\w\$\[\033[m\]'
                 ;;
         *)
                 # Cyan prompt, time printed in top right hand corner (36 denotes cyan)
                 export PS1='\[`tput sc;tput cup 0 71`\t`tput rc`\]\[\033[36m\]\h:\w\$\[\033[m\] '
                 ;;
         esac

I only use xterm, not any of the other terminal apps.
