It's perhaps worth a reminder that, in the sense 
that you mean it, spreadsheets can never be 
"trusted". Since much of their essential 
functionality is hidden (formulae, formatting, 
significant options) and they are untestable, you 
should never rely on the results of a 
spreadsheet. Your judgement, then (but not mine) 
is that spreadsheet programs generally are "totally worthless".

See, for example:

"I will happily use a spreadsheet to estimate the 
grades of my students, my retirement savings, or 
how much tax I paid last year… but I will not use 
Microsoft Excel to run a bank or to compute the 
trajectory of the space shuttle. Spreadsheets are convenient but error prone."

"But while Excel the program is reasonably 
robust, the spreadsheets that people create with Excel are incredibly fragile."

http://mba.tuck.dartmouth.edu/spreadsheet/product_pubs_files/Literature.pdf
"Among those who study spreadsheet use, it is 
widely accepted that errors are prevalent in 
operational spreadsheets and that errors can lead 
to poor decisions and cost millions of dollars."
"Panko summarized this literature by reporting 
that 94% of spreadsheets have errors, with an average cell error rate of 5.2%."
