Agreed. Have you seen the Nspire CAS? It's pretty amazing.

I've seen images and demos of them, just not in person. They do look very interesting. I'd love to get my hands on one.

I have got an older (2006) NSpire CAS with OS 3.2 which I rarely use other than for working out integrals/differentials when I get stuck with pen and paper. TBH the Nspire CAS is large, clunky, complicated, unintuitive, eats batteries and is not a whole lot faster or more functional than a TI89. I still however, use a TI86 all the time out of choice as the stat graphing is great (I mainly use it for regression analysis), it does base-N very well, has conversions built in, has a good solver and the programming language is simple enough to fit in my head. I have a fairly large set of programs I've developed for the TI86 as well for dealing with navigation/triangulation/mapping.

  The Nspire CAS is really more of a tool for students. I'd call the point-and-click interface clunky and intuitive--it's not hard to figure out how to do things, it's just going to take you a while to get there. :) I'd imagine if you have software you've written for the TI-86 and are inclined to do integrals and differentials on paper until you get stuck, it's probably not the right tool for you. :)

    I agree with you there about the student comment! I do find it poorly integrated though, for example: To do a linreg on some data and project that past the extents of the dataset requires... NSpire: create document, create spreadsheet, enter data, create stats plot, analyse->regression->linreg, create graph, plot stat func, set zoom constraints, whack X value in, read Y. That's just shit, student or not. TI-86: {1,2,3,4}->xStat, {3,6,8,10}->yStat, catalog->LinReg, Graph, zoom, enter X, done. Probably right about it not being the right tool. Anyone want to buy an NSpire CAS? £30 including delivery to the UK :)
