What was your favorite product at CES ?

One thing I'd thought about for years finally appeared at CES. They had a mister you attach to the outside unit of your heat pump. It included the deionizer/water softener to prevent the minerals from building up on your A/C.

But then the company ruined it by selling it only as a $100/year service.

I bought a pair of those several years ago. It worked for about a year and then broke down. I tried to sell the remaining unit for 90% off on craigslist, and there were no takers. It was the kickstarter version 1.0 of this:

Everything that I saw announced felt uninspired/tepid/meh or an incremental update to something nobody needed. It was pretty... boring.

Take note, we're near the peak of froth.

- 8K TV with HDR going to 10000 nits. Where bright objects actually do look bright.

- The new LG Gram ultralight laptop.

- On-screen fingerprint scanner.

- Intel's voxel tech, but that's a very expensive system.

- Pretty much all of NVidia's machine learning tech.

- The dual-perspective projector system, very clever.

From all the stuff I saw on CES this is the only thing which I _really_ want.

Apparently it uses IR and is easily fooled. I think Android manufacturers have it right by putting the scanner on the back or side. We can keep our good capacitive fingerprint sensors and still get bezelless displays.

I wonder how far off a transparent digitizer is that can make out fingerprints?

Any that worked when the power went out.
