It would be cool as well if SQL Server recognized that a column sorted by datetime is also sorted by date and could leverage this in a "GROUP BY CAST(OrderDate AS DATE)" or when merge joining against a table with dates. The sargability of casting to date should probably not be relied upon though. It reads a larger range than optimum and also can give much poorer cardinality estimates (More details here http://dba.stackexchange.com/questions/34047/cast-to-date-is-sargable-but-is-it-a-good-idea )

(it’s worth noting that the ‘date’ type is new in SQL 2008. If you’re on SQL 2005 still, then you won’t be able to run the query that uses it)
