I was initially very skeptical of Office 2007 and Excel 2007 above all, but I quickly changed my mind, the reasons being those cited plus1 - The same keyboard shortcuts of 2003 work in 2007 (i.e. Alt+E, S, V to paste values only, Alt+D, F, F for auto filters etc)2 - You have a lot more rows and columns in 20073 - Filters are better, there are extra formulae4 - By doing Options, Customise, you can create your own toolbar with shorcuts to all the things you use the most and these will always be displayed no matter which tab of the "ribbon" you are displaying.
