Totally worth it

About 2 weeks after buying a TI-89 titanium, I found this app. I wish I had found it before I bought the outdated, yet still overpriced calculator.
You can write your own programs for the calculator within the app and you select all the functions of the language from the menus, so its relatively easy to get started.
After a few days of using this app, going back to the calculator makes the old TIs shortcomings painful:
- the backlit display on the iPhone is great, the calculator has no light and is difficult to see (both the screen and the keys) without very proper illumination
- the touchscreen makes it a much faster interface, and zooming in and out of graphs is awesome on the app and painful on the calculator
- the ti calculator is sloooowwww. Graphing and zooming is immediate on the iPhone but takes several seconds on the ti
- the iPhone is already in your pocket and you dont need to take the bulky calculator or buy AAA batteries

I really dont know why these calculators still cost so much. They are the same price theyve been for decades, without improving their technology, speed, memory, size, screen or software. With the vastly superior iPhone being basically free now, I thought this very old calculator design wouldve deflated to maybe $30 or $40. But no. The only reason why you might want to buy the actual calculator is if you need it to take tests in school, as some require a ti.

For this app, I just wish there was support for the programmer, and a way to write and test programs for the app on the computer and then upload them, because switching keyboards on screen and typing with your fingers is not great.

Bottom line: get the app, you wont regret it
