This is kind of a hack of case, though. I think what the OP was looking for is
 isPalindrome word
  | (word == reverse word) = putStrLn (word ++ " is a palindrome")
  | otherwise              = putStrLn (word ++ " is not a palindrome")

Erm?  It's as much of a hack of case as yours is, since the above is actually using case.
