Texas Instruments - TI 84 Plus Review

I have owned the TI 82 and TI 83S Silver Plus before this. TheTI 84 is another wonderful product from Texas Instruments for the student in high School or College student. Any complaints about speed is irrelevant. I personally found the TI 84 very easy to read, fast, nice case-I like it better the TI 83 Silver case-and it included some programs that were not on the TI 83. It is supposed to have other stuff that the TI 83 did not have but I did not notice this. This is because I bought it to assist me in Algebra, trig and etc. For the money it is a great investment and a very useful tool. I will say that one area I noticed a great difference in was viewing the window. For me, (and I wear bi-focals) the TI 84 was noticeable in its clearer image and etc. Hope this is helpfu.
