First my reference system: black matt case, 1kg, 14” non-blinking Low Power LCD, 73Wh battery, practically no holes on the bottom, hinges opening with 180 degrees, etc.

Now let’s look on the market.

Few years ago Intel created X86S standard, where proposed removing some obsolete modes and instructions. Was it implemented? No.

Apple is preparing laptop with phone CPU, Android phones can be connected to external monitors and keyboards, laptops are used instead of desktops for gaming and there were some initiatives like Nextdock, where phone is connected to "notebook-like" case.

Where is currently border between all device classes?

Let's look on some thing:

Model	Battery	Screen	Weight
Fujitsu Zero	31Wh	14"	634g
Fujitsu FMV Note U	64Wh	14"	848g
Toshina Portege X40L-M	65Wh	14"	from 875g (some docs say 1050g)
Asus Zenbook A14	70Wh	14"	990g
Clevo (the whole series including L14xMU)	72Wh	14"	990g
GEEKOM GeeBook X14 Pro	72Wh	14"	999g
HONOR MagicBook Art 14 2025	60Wh	14,6"	1030g
Macbook Air 13 M4	53,8Wh	13,6"	1225g
Framework 13	61Wh	13,5"	1300g
upcoming Dell XPS 14	70Wh	14"	1380g

Do you see pattern? Why so many Asian laptops can have max. ca. 1kg and it's so problematic in US?

Fujitsu (Japan) could sell millions of devices... if they only want.
