Microsoft Excel for Mac is UNBELIEVABLY bad
Many of the really useful keyboard shortcuts have been eliminated. Actually, it seems that there is a direct correlation between how useful a shortcut is and how likely it is to have been eliminated in this version of Excel. For example, to sum a column of numbers on a PC, you could type alt+=. On the Mac, you have to use the mouse to go to a button on the toolbar or else physically type something like =sum(a23:a31). Who doesn't want a keyboard shortcut for summing a column of numbers in Excel?!?!?
Excel for Mac allows you to reassign keyboard shortcuts -- but only on a very limited basis. For instance, you can't reassign any of the really useful ones, like editing the contents of a cell (F2 on the PC) or redo (F4 on the PC). I can't believe that these don't rank among the most important functions for the average user.
One completely non-sensical change that defies any possible rational explanation is the Print Entire Workbook function. If you have multiple tabs, it will print the tabs in descending order (tab 1,2,3,4) while the pages are printed in ascending order (page 4,3,2,1). So unless you have some equally strange system for arranging your tabs and pages, your print-out will be completely out of order.
I don't know if anyone actually prefers typing CMD+C and CMD+V for cut and paste as opposed to CTRL+C and CTRL+V with a PC. I find it extremely awkward, even after using a Mac for about the last 8 months.
If I am mistaken about any of these flaws, someone please let me know.
