Put this in your .emacs

(setq read-buffer-function 'read-buffer-different)
(defun read-buffer-different (prompt &optional default require-match)
  "Read buffer with minibuffer completion not including current-buffer."
  (let ((bl (buffer-list))
        (cb (current-buffer))
        buf dbl)
    (while (setq buf (car bl))
      (unless (eq buf cb) (push (buffer-name buf) dbl))
      (setq bl (cdr bl)))
    (completing-read (if default
                         (concat prompt "(default " default ") ")
                     dbl nil require-match nil 'buffer-name-history default)))
