Is the TI 89 still useful or not?

In summary, the conversation discusses the recommendation of using a TI 89 calculator for a first year Petroleum Engineering student. The student is unsure if the TI 89 is necessary and is considering the options between a TI 89 and a TI 89 Titanium. They prefer the styling of the TI 89 but are concerned about potential performance differences, specifically the lack of a root ability in the regular TI 89. The conversation also mentions a comparison between graphing calculators and smartphones for testing purposes.

I am a first year Petroleum Engineering student and I currently use a TI 83+. However, the TI 89 comes recommended from my math professor and TA. I have two questions:

1. Should I get one? It is that much more useful? How so? Pros and cons?

2. Should I get a TI 89 or a TI 89 Titanium? I've used 84's and I dislike their bulkiness and their buttons, so I lean towards the TI 89 which uses the same styling as the 83. What about performance differences? I hear that the regular 89 lacks some kind of root ability.
