But the Elitebook Ultra G1i isn't even clearly better than the Elitebook X G1i, based on the reviews I saw. It does have an OLED screen and a haptic trackpad, but the screen is also very reflective, and the key travel is only 1 mm. In my opinion, HP should combine these two lines to offer one truly premium product - especially given that they both cost over $2500.

Another thing that makes HP's current naming confusing is that the Elitebook X G1i is completely different from the G1a, which targets more performance at the cost of being 250 grams heavier. It should've been part of the ZBook lineup instead.

I am surprised that Mr.Ngo would feel its baffling to understand. Actually HP's name definition is crystal clear.
For Elitebook only: From flagship to lower end should be:

1. HP Elitebook Ultra G1i=Ultra=Flagship, aka: New machine to replace Dragonfly series, G=Generation, 1=specific mk variant, i=Intel. For C-Suites.

2. HP Elitebook X G1i= Executive Premium business machine, X=10=1000 Series, G=Gen, 1=mk1,i=Intel, for higher manager purpose

3. HP Elitebook 8 G1i=800 series, major series of Elitebook, 8=800 High-end

4. HP Elitebook 6 G1i=600 Series.

As for ZBook Ultra G1a=ZBook flagship Generation-mk1-AMD Based.
Very straightforward
