Thanks, that's the kind of feedback I need. For developing while not travelling I currently use a Macbook Pro 2015 with 16Gb of RAM and I'm happy with it, and I've previously used Windows or Linux desktops and laptops, so I'm OS agnostic, I can be productive with any OS (on Windows I'd just install cygwin with console2, or cmder, or lately Babun which is a preconfigured cygwin with a package manager). I remember the time years ago when I was programming with 1Gb of RAM (that was the normal for computers at the time) and it was a painful experience with Eclipse and other tools. As computers evolved with Moore's Law, 2Gb was a better experience and I think 4Gb was fine at the time. Then 8Gb should definitely be good and 16Gb is plenty even to run VMs. Thinking that it would not be for a full time developing environment, just to be able to do some work while travelling in a long trip where I don't want to bring an expensive laptop like a Macbook Pro, I thought 4Gb might be enough, so your feedback is really appreciated.
