1. Really, really great looking graphs. Excel fails so hard at this it's unbelievable. 2. Easy navigation. The giant spreadsheet model is a very simple metaphor but sometimes I'd like a way to jump to different parts of it more easily. 3. Not be a spreadsheet. The one-big-sheet model might be better represented as a bunch of smaller tables floating in space with formulas interconnecting them. The letter/number convention has been around since the very first spreadsheet, surely we can do better. 4. Understand the internet. RSS, live stock quotes, etc. The address of a cell ought to be internet-compatible somehow, e.g. http://myspreadsheets.com/daily_report/C2 http://myspreadsheets.com/daily_report/C2 or http://myspreadsheet.com/daily_report/mynamedtable?x=Jan2007&y=profit http://myspreadsheet.com/daily_report/mynamedtable?x=Jan2007.... Google Docs does something like this, I think. 5. Allow scripting in a language that doesn't completely suck. Javascript or python would be good choices.
