I try to buy expensive things when I want to go to my grave with them, and I think this is no exception.
I knew I was getting a beefy graphing calculator, but I didn't expect to receive a NASA micro supercomputer! This thing is INTENSE. It has a touchpad for controlling a cursor! A CURSOR. ON A CALCULATOR. My mind has been shattered.
It's very daunting on first use, though I suspect I'll know it like the back of my hand after some practice.
Build quality is phenomenal. You wouldn't think a screen could look "premium", but you really do get what you pay for here.
