I downloaded Open Office. The spreadsheet is extremely limited wrt Excel and I couldn't find any Basic for Applications equivalent- so no fancy self programming seems to be available (it's a tiny application, after all).  No 3D chart plotting either.
I think TNSTAAFL applies here.

I've said that OO does everything I want it to, which is true. Yes, there are features in Excel that are missing from OO, but they're not features I would use. I only use spreadsheets for fairly basic stuff like calculating tax, and the 3D spreadsheets in OO are plenty good enough for that. I don't need 3D plots.

Lotus 123 is still the best spreadsheet I've ever used, though.
