We have several users who've been using Lotus123 for years now, and they aren't happy with switching to Excel due to the vastly different user interface. As we all know, Lotus is dead. Is there another program besides Excel that is similar if not identical to Lotus123 (for spreadsheets)? If not, is there some type of add-in or complementary program for Excel that would assist users of Lotus123? Something like an overlay of the Lotus controls and shortcuts in Excel?
