Lighter T16 Gen 4?

Hi, I was looking to buy a Thinkpad. I come from an HP Elitebook 855 G7.

The T16 Gen 4 with AMD Ryzen AI 5 PRO 340 caught my eye, for the:

• nice screen size
• extensible RAM and disk
• no dedicated GPU
• the processor seems nice, future proof and not too power-hungry

The only things that worries me are the weight and build.

Earlier versions used alluminium, and the weight is 1.77kg which is a little heavier than what I had.

Are there any similar laptops that are lighter to carry around? Does the build quality feels cheap?

I thought about the T14 Gen 5 AMD, but the screen size may be too small for what I'm used to. I also thought about the X1 Carbons, but they too are 14" and don't look that extensible.

Thanks for the help :D
