Those times are less rare than you'd think. I've been in plenty of situations where I've needed to develop something in an environment with sketchy/nonexistent network access. Not to mention that even in ideal conditions you're now maintaining two separate machines instead of one, and not to mention that if you're doing all your development over VNC or RDP or something you're now introducing some rather annoying latency between your fingers and your eyes. Having done development work by remoting into another machine (specifically, RDPing into a "dev" server to use vendor-specific IDEs/tooling), I can't say it was an even remotely pleasant experience. I would've sooner preferred doing that work directly on my own machine, or at the very least in a VM if a specific OS and configuration is necessary.
