Computational Statistics & Data Analysis recently devoted an entire issue to Excel 2007. A good example of general opinion can be seen in the paper by McCullough and Heiser (2008) "On the accuracy of statistical procedures in Microsoft Excel 2007". http://dx.doi.org/10.1016/j.csda.2008.03.004 From the abstract: "Excel 2007, like its predecessors, fails a standard set of intermediate-level accuracy tests in three areas: statistical distributions, random number generation, and estimation. Additional errors in specific Excel procedures are discussed. Microsoftâ(TM)s continuing inability to correctly fix errors is discussed. No statistical procedure in Excel should be used until Microsoft documents that the procedure is correct; it is not safe to assume that Microsoft Excelâ(TM)s statistical procedures give the correct answer. Persons who wish to conduct statistical analyses should use some other package."
