I agree with that. The and = ... wasn't really an improvement over and xs = ... xs, and if the later is easier to read that's good.
Btw.:
What happened to isSpace, toLower and toUpper (, from the tutorial)? (I)sSpace must be there for words anyway, so I can't see why it's missing. (T)oLower and toUpper might have some subleties with internationalization and stuff, but they would be useful for me even as a poor man's version which can just convert "A-Z", "a-z" and no umlauts.

I feel that Haskell is missing some basic string manipuation functions, like - replacing all occurances of one substring (or sublist) with another string (or list). - tokenize a string by an arbitrary delimeter
I know many of these functions can be written in Haskell without much effort. But I don't really want to "invent" isSpace for any program.
