Your Ti-Nspire programs are my drug of choice, they are addictive, will enjoy them for rest of my life

Thank you.  I had been hesitating to make the purchase as I had wanted to get the apps for TI Voyage 200; 

but I decided to get the ones for TI-Nspire CAS CX instead, basically because it has more memory available.   

These apps you sell have the potential to become addictive so I most likely will be back for more!  

I think I made the right choice.

So, needless to say, I am very impressed.

Beauty is in the eye of the beholder.  Your programs are my drug of choice.  

I am sure to enjoy them for the remainder of my life.  

They are one of the few things worth buying besides food and a good pair of boots.

Impressed with Calculus Made Easy for Ti-Nspire

Hi Mike

I was so impressed with CME that I bought AME and PME and they are both first-rate.

I’ll be buying more as they appear.

Your apps have made the Nspire a lot more useful to me than it was – in fact, I’m beginning to like it quite a lot.

Congratulations on the hard work, I suspect your nspire apps will be even more successful than the Ti89 apps.

Best wishes
