After my old Ti30 had now given up from the secondary school and high school years, both their mind, I wanted to buy the same computer again. But not there. So I bought this. One can argue about the design. I think it's not so great. More like a designer piece and the shell is not as convenient as with the older Ti30. What I also do not like so that the operation has Teilwiese fundamentally changed. I used to have, for example, 45 and then pressed sin to calculate the sine of 45 degrees. Now I have to sin, and then enter 45. Is certainly a matter of taste, but if it had to be?
Otherwise, I think it's very nice that you remain the old entries stored in a history and at any time can be referred to again. And then the way of writing formulas as they are in the books. With broken strokes, radical sign ...
Another small drawback: In low light, I am always afraid that the computer could run out due to power shortage. Although did not before, but the feeling still remains. In my last Ti30 button cells were installed. They held some 20 years !!! Whether solar cells make more environmental sense for so long battery lifetimes?
