$50k is pretty damned affordable. I mean, it's not dirt cheap, but the roads are full of cars and trucks that cost that much and aren't nearly as innovative.

My car has RFID keys, with doors that can be unlocked via proximity. (There's a button on the door handles, and on the trunk, that unlock things if the key is in range.)

The range is actually pretty short. Maybe 3-4 feet. Also, it's directional. If you're behind the car, you can pop the trunk, but you need to be beside the door to unlock the doors.

If you're inside the car, then the outside sensors don't work, because the key isn't in the right spot. It's inside the car. As such, you can lock the car, and the outside buttons won't function, since the key is not in the correct position, outside the door.

It's a reasonably well thought-out system.

The thing with audio is that you quickly reach a point of greatly diminishing returns. The gap between $50 and $500 headphones is enormous, but at levels above that, I struggle to hear a difference outside of contrived tests.

I have Senn HD650s and Shure SE530s, and would recommend either without hesitancy.

HP 12c for financial calculations

HP 50g for math/science/physics

R for complex statistical or financial calculations

Octave for complex math/science/physics calculations

And fuck all the TI calculators. I wish I'd never owned a single one of them. It's hard to realize what trash they are until you get used to the HPs.

Well, from my personal account I can just scan the check. USAA offers this.

From my business account, I don't even need to bother with the scanning, if I don't feel like it.
