I´ve worked with the Nspire. I found the nspire very very useful for maths and very very useless for programming and games and any thing but maths. The nspire has almost none programming functions. There is Disp — For/EndFor — While/ EndWhile — Loop/EndLoop - Try/Else/endTry — Return — Exit — Label — Goto — If-Then-Else-EndIf. There are some more but i dunno what it means. There are also math command like max( . mean(. abs( seq( and all the string commands: instring - left - mid -sub ……
There is no: Input - Prompt - Repeat or any kind of graphical commands such as Line PntOn, Horizontal.. you get the point ;)
Some basic 'nspire-technology'. There is NO homescreen. Every thing is in documents and there is ALWAYS ONE document open. This is very frustrating to work with cause you cant go back to what the TI84P has, a homescreen.
a document excist of X problems with each problem Y pages. There are 5 different 'kinds' of pages. Notes (just letters and symbols, no function). Calculator, just a normal calculator. You prmgs in here. Graphs & Geonometry, graphs… but very detailed and with many options and functions. Such like moving with the cursor and drawing a triangle, this goes nice and smooth on the nspire. And such like an automatic area calculation which updates when you grab a point of the triangle and move it.
You also have an matrix-kinda page. Matrix with inprogrammed upper row, and first colomn. Not very handy.
and the 5th option for making a page is an program or function. Function is the same as a program but (i thought) functions can be opened in Graph&Geonometry. The programing is very poor. First line is:
"yourprogramname"(variables)= here goes nothing… :/ right…
Here follows your program..
Example:
testprog(a,b,c)
Disp (-B+wortel(B²-4A*C))/2A
@an other page you type (there are letter buttons!! see images.google search TI-Nspire for pics)
testprog(1,2,-8)
You'll get .. uhm.. 4 (or -2 i dunno , this doesnt matter)
Wait there ARE things that are great about the nspire.
Scrolling between pages is quite simple and you can store things into variables. (use 'arrow' or :=) There for you can link a variable which you enter in a matrix (or in calc-mode) store it in a or ab or variable1 or G6. Variable you can name yourself, that s handy. This variable you can use in G&G mode in which you can draw almost everything. And connect this variable with for example a pillar.
the nspire is priced like the 84Plus SE.
The linking software is 199,95 times better then TI Connect. (works perfect) And with a legal buy of this thing ull get an emulator software. (and some booklets and cables etc etc)

this atomiclearning is a really good tutorial site which includes everything of the nspire (and CAS) and has movies which are easy to follow.
The graphics of the nspire are great. For really measures and stuff i guess you can browse wikipedia or google?
I dont know if you can use your nspire in the exams at school. Here in the netherlands (won 3-0 vs the worldchamp italy!! :D) is it illegal. And i dont think the nspire is ever gonna be legal for exams cause you can simply copy paste whole books in this 'calculator'.
I've recommend some other ppl to buy to TI84Plus SE in stead of the Ti Nspire but you already own the 84SE, if i were you i wont waste the money. The TI84Plus is never gonna be old, except if TI comes with an 85 but the nspire is no replacement for the 84/83
I hope you've gotten some clearer vision of the nspire and what to do. If you have futher questions… post here? browse the sites. Or post @ http://www.ti-nspire.com/tools/nspire/resources/interest_form.html
these people really know the nspire.
