What can't you do in Excel?
LogicHoleFlaw: I'm exactly the opposite of your target audience with this question, but hopefully I can give a useful response anyway :)I know almost nothing about Excel and it's a deficiency I feel quite keenly. The program is almost completely undiscoverable to me and I don't even know where to start with it. I know that there are powerful uses and features of Excel but the model (or at least the bits of it I've been exposed to) hasn't clicked for me yet.I suspect I'm not alone in my bafflement; maybe there is the possibility this new spreadsheet could be useful to us  Excel-ignorant customers who nonetheless want access to the benefits of this class of software.As a hacker and programmer who is comfortable with all sorts of paradigms I feel really strange admitting this weakness but I suspect that I'm not the only one who is in this boat.
