I dont really want to defend Excel, but "Sorting can be limited to one column" is true if the data is not contiguous but excel 2003 onwards gives a warning - 256 wide is true until Excel 2007. 2007 can access 16000 columns and 1048576 rows. SQL and XML data access allows this to be broken form Excel 2003 onwards
