It's a fairly recent, 2021, ASUS TUF F15. Soldered RAM is not really that common, as I've upgraded the RAM on a great many, both mine and those of others. I think it's in some of the lower-end models, but in my many years of working with computers, both desktops and laptops, I've never seen it.
I almost always have many apps open at any particular time, usually the same ones, and with a Qortal node running that can use 50% of my total RAM, and it does bog down a little sometimes. Yes, I'd also need to open lots of tabs in Brave, as because I rarely use it, it has maybe one or two opened. 😁 🙏 💚 ✨ 🤙
