I don't need to fuss with file syncing solutions because I only ever access them from the one machine, I just happen to access that machine remotely. Backups are seamlessly handled by Linode snapshotting my disk every so often. I can happily run little webservers, etc, with pretty decent availability.
The thing that sits on my desk is a second hand, small form factor ThinkCentre I picked up dirt cheap when some corp was done with it. All it needs to do is run a terminal ssh'ed into a Tmux session and a local instance of Firefox. I get basically the same experience whether I'm at my desk, on my iPad or using Blink on my phone.
It's actually made me _less_ concerned about my unreliable broadband connection. If my main link goes down, I just hotspot to the 4G on my phone. The latency is a little worse but the bandwidth isn't actually relevant. All my chonky uploads like build artifacts, docker images, etc, all go direct from my Linode to wherever they need to go. Very civilised.
