War on Calculators

[JimP]

At least a separate graphing calculator can't be used to text or otherwise communicate in an irrelevant manner like a smartphone can (can it?)

But as for TI -- I acquired a TI-89 Titanium model just to play with it and found it a real struggle. Having grown up learning that to calculate the sin of 29 degrees one could press the number 29 and then hit the sin key, and get an answer immediately, the TI system was dreadful. One has to spell it out as Sin(29) and then hit Enter. Not Efficient. Long live HP!
