I think that's definitely one of the good use-cases of a portable machine. Before buying a new one, I did do the maths on using a more powerful desktop instead and just keeping my older laptop for travel – but like you say, it means constantly thinking about what data and capabilities you have available at any time. And coincidentally I was also working last week on real-time computer vision for robots, on a remote customer site, so it was nice to have my machine with me :)
