The death of calculator market?

[Thomas Radtke]

I'd rather not like to see students with tablets in the classroom. Minor problem: "I forgot my calculator." (usually one student) Major problem: "My battery is empty/tablet is broken." (a lot more students if using tablets I fear)

Nice if they all use the same calculator. Ultranice if that calculator could do basic spreadsheet things (for physics curriculum).

This is new (to me) insight after I was a teacher for five months (math and physics).
