The death of calculator market?

[BillBee]

I use a 11c (now a DM15) for work. Usually stats stuff ~ Student's t, or running discharge limit conversions from mass to concentration based. (On special occasions a ft^2 evaporation rate). Of course everything is first in Excel but (to me at least) it needs to run through the Hp for approval.

Working through a few used text books during the past months and I have found that one has to have a graphing calc. Many problem sets throw graphing calc (scatter and function) problems in there. Much different than my days in class where everything was on graph paper.

The phone apps are great but I did run into a problem of answering the cell and while opening the Free42 app did manage to hang up. Yes, user error.
