I care. It's a poor choice of wording, and it's apparently a redefinition of the term spreadsheet.

I believe that they are alienating users who might read "spreadsheet" and think "a bunch of formulas that I don't know how to use" rather than "easy to use layout/calendaring/organizational tool." Furthermore, those of us who read "spreadsheet" and think "oh, awesome, tablet optimized spreadsheets!" are sorely disappointed.
