Keep in mind too for SQL Server the case sensitivity is based on the collation. The default collation is case insensitive - but this could be changed to be case sensitive. A similar example is why do the default Oracle databases use a Western European character set when UTF is required for global applications that use non ASCII characters? I think it's just a vendor preference.
