Well, actually, there are a number of cases where PreparedStatements are useful (this list is not complete, but just to name a few):

- The JDBC driver handles escaping the data. You mention BLOBs, but Strings will be escaped automatically as well, which you would have to do yourself when concatenating.
- Performance: The RDBMS can cache the query, instead of calculating an execution path for every time it's called. Whenever you re-execute the PreparedStatement, the JDBC driver only sends the parameters. When running the same query (with different params) a large number of times this can increase performance quite a lot.
