I personally found it very difficult to remove the expansion cards using one hand on the release button, and one hand on the card. Some may have already found this out by experimentation, but I think it’s much easier to use two thumbs (one on each side of the card) with your left index finger pressing on the eject button. Maybe it’s just me, but this took me about 5 minutes to figure out.
Nice pics! After a bit of practice, I’m able to get the cards out with the laptop upside-down on my lap quite consistently for easy swapping. Already switched the charging port side quite a few times, which is such a nice feature.
After a few months of this, you get used to a single handed removal with the laptop right-side-up by using one finger to press the release button and the others to slide the card out!
This helped me too. Having to test my system without any of the expansion cards connected and I was really struggling with removing them, this helped immediately!
