Digital Nomads

Hi guys, title says all. I've been waiting for such a product for YEARS, literally:

• There are 15.6", 16" and even 17.3" touch monitors
  => So it's not a matter of touch panel size
• There are 1080p, 2.5K and even 4K touch monitors
  => So it's not a matter of touch panel resolution
• There are 15.6" touch + battery monitors that last for many hours on battery, and 16" is very close to 15.6"
  => So it isn't a matter or power draw
• A 16" 2.5K Touch monitor can weight as little as 0.9 kg. With a battery it would be about 1.1kg. Less than a 17.3" Touch monitor.
  => So it isn't a matter of weight

For some weird reason, NOBODY is making a 16" 2.5K Touch + Battery monitor. We can get 3 of these four features, but never the four of them. This situation hasn't changed a bit for the last four years.

I wonder why, and I'm growing increasingly desperate here. Any hints? Thank you.
