Some of my friends who are really into keyboard nerding look at me funny but I've been on K400 Plus for like half a decade by now. It fits in a bag and costs like 30-40 bucks, and it has touchpad for webshit like Jira that can't be driven through Vimium and other keyboard maneuvers.

I mistreat it heavily, like dust, crumbs, drool and so on, and still I'm on only the second one. It weighs little so it's easy to put in the lap and move around to get some ergonomics for the wrists going even though the touchpad part sticks out on the right hand side.

Can I push four keys at the same time and get something out of it? Probably not, but it's not something I feel like I'm missing out on. I push a key, it sends the bytes, the operating system does what I told it to, that's good enough for me. In case I break it I'll be like 'yeah whatever' and order a new one. It's cheap enough that I could have like four for the price of something cool.
