TI-nspire CX CAS Calculators

I am currently in a 10 day workshop at Steven's Institute for C-TEAMS in math.  Curriculum topic study to enhance achievement in mathematics and science.  We are studying the algebra curriculum in K-12 with vertical articulation.  The workshop has received the new TI-nspire CX CAS for us to test out.  These calculators are built on a Computer Algebra System and they are incredible.  They have a color screen that is built on a computer platform.  The calculator can factor polynomials, solve for roots, use the quadratic formula, factor numbers to prime numbers, etc.  This calculator can solve equations, integrals, and solve other calculus level problems.  This calculator can seriously do it all.  It also has 3-d view graphing and everything can be saved to a computer for future use.  The other thing that is great about this calculator is the classroom lab station.  These calculators link to the instructors calculator via the computer.  The teacher can then send questions out to each user and each user can respond within the calculator and the teacher receives their answers.  This calculator could be used to take tests, quizzes, etc.  It has a student response system built in.  These calculators are about $140 each but well worth the purchase.  It is something I am interested in getting a grant or a donors choose project to fund.  If you have the chance check these calculators out!
