Deletion of Comparison of Texas Instruments graphing calculators

Comment: Since TI has been making graphing calculators for so long, and since they have become an integral part of school curriculum, we should have an article on them.  The article could be expanded to be a comparison of graphing calculators in general if that would make it more useful.  I used this article today to evaluate the suitability of a different (older) TI calculator than the one taught in school for a particular student.  The market does not provide such comparison information across the historical spectrum of products.  If citations are needed to subdue the |ORIGINAL RESEARCH claims, then we should add citations. The prices are of modest historical interest

Comment: it's a pretty piece of |ORIGINAL RESEARCH, smartly presented. Unfortunately, analysis of the relative merits and purchasing price of a |CATALOGUE of a manufacturer's products isn't the business of Wikipedia. I do hope the author won't be too disappointed and will put his undoubted energies into improving any of the many articles which could benefit from this sort of editing skill

Comment: Article appears to compare difference versions of Texas Instruments graphing calculators. While I think the article was created |with moral intentions and not  |created for commercial purposes, the article lists prices and only mention Texas Instruments products. Prices violate  and listing only Texas Instruments may suggest that Texas Instruments is the only corporation that makes good graphing calculators, which is |an opinion. Furthermore, the lead appears to consist solely of |original research
