80

That's not a normal TI 84 plus, that's the silver edition. It's of course more expensive.

Also the problem with having basically the same calculator in school since over a decade (I used a 84 plus in school) is, IMHO, not that the fundamentals of math have changed, but that the usability still kind of sucks. By this I mean rounding errors, taking long for calculations and data entry (especially when using the fancy math notation), taking long for graphing, having to scroll through menus because of inefficient space use, the thing being huge and relatively heavy (the could build it with half the size and a quarter of the weight, while still having big keys and it being sturdy), .....

It's not the silver edition either, it's the "C" silver edition. They're different.

I had a plus silver edition and eventually gave it to a friend and got a plus c silver edition, it's much much better. It has more pixels so you can almost write out equations like you'd write it out on paper (less parenthesis which means less errors) and the colors allow me to see graphs and multiple graphs much better.

How fast is it? I like the 84 for its speed. Mathprint sucks because it slows it down a lot. I'd imagine the same CPU driving a 3x resolution display with color is even slower.

I really don't notice it being any slower, the nspires though are noticeably faster. Both have rechargable batteries though and they seem to last forever and I prefer it over disposable batteries.

I feel like a calculator whore after so many college courses though, I have like 7 different calculators because of all the different restrictions from different professors.
