I am currently a freshman ECE major. Since my TI84 broke just recently, I am in market for a new calc. I have narrowed down my choices to 2 models, the 89 titanium and Nspire CAS with touch pad.

[Amazon.com: Texas Instruments TI-89 Titanium Graphing Calculator: Texas Instruments: Electronics](http://www.amazon.com/gp/product/B0001EMLZ2/ref=ox_sc_act_title_2?ie=UTF8&m=ATVPDKIKX0DER)

[Amazon.com: TI-Nspire CAS with Touchpad: Electronics](http://www.amazon.com/Texas-Instruments-N2CAS-CLM-2L1/dp/B003EK7O1G/ref=sr_1_1?s=electronics&ie=UTF8&qid=1301813668&sr=1-1)

The easy way to go is to get the 89. But buying yesterday tech(2005) makes me wonder if that’s a good decisioin. The Nspire is faster than the 89 in every single way. And from my limited experience, the 89 is actually slower than 84 for simple calculations.
