fish. I think it has most things i want out of the box, so it should be simpler and snappier than my zsh setup. it's just that zsh hasnt bothered me enough to try it yet.
also nushell, im interested in the idea of manipulating structured data instead of unstructured text
My reasons were more hardware related. When I was a bit younger my parents gave me a netbook which had 32 GB of storage, and Windows used almost all of it. I wanted to do creative projects in my free time, but I couldn't install programs or save any of my work. I would often restart to clear log files and gain a bit more working storage, which was extremely annoying because it took like 5 mins for the computer to finally settle down and be usable.
I eventually got a 32GB flash drive which helped a lot, but it was not enough. With 4GB ram I could only have about 3 browser tabs open, and not all the programs I wanted could be run off the flash drive. It was still resource management hell.
Somehow, some way, I learned about Linux. I got a 128GB microSD, put Mint on it. It truly set me free. I could install the software I wanted, I could make the things I wanted to make, I could open more programs at once, and I could do it all without unbearable lag. I never looked back since.
