My employer provides me with an iPad Pro and rather than carry around an additional laptop I run x86 systems (Linux and Windows 10) using QEMU-KVM on my ridiculously overpowered home server and remote desktop to them from the iPad Pro.
For software I use Jump Desktop. On Linux I connect via VNC and Windows I use their custom Fluid protocol. For keyboard and mouse I use an Anker Bluetooth keyboard and mouse is a Swiftpoint GT.
Latency varies a lot and I’ve found hotel WiFi to sometimes be unusable. ATT LTE on the device generally works pretty well. I’m primarily running this setup just to have access to a full browser environment for my tinkering with web scraping so having a super responsive low latency connection isn’t as vital as it would be to do something like gaming. The main drawback is always needing a solid connection which is mostly solved with LTE where I go.
