Excel 2003 versus Excel 2007 There are many differences between Excel 2003 and Excel 2007. Some of the changes in Excel 2007 are improvements. Some are a major step backward. We'll leave it up to you to decide which is which. The following are some of our major findings when we compared Excel 2003 to Excel 2007. We do recommend that if you have Excel 2003, that you do a custom install of Excel 2007 and tell it to keep all prior versions. This will allow you to use your prior version if you need it. The default installation of Excel 2007 automatically removes all prior versions. We think having the prior versions around is a good thing. Probably the best approach is not to upgrade to 2007 until forced to do so. And hope that Microsoft will release a decent upgrade soon and the first time (versus waiting for an SP2 version, which would patch the patches) (Xem bảng so sánh tại đây) Qua bảng so sánh trên chắc các bạn cũng đã biết thế mạnh của Excel 2003 và có nên nâng cấp hay không?
