I tried a Surface, but didn't like it enough to keep it. I did not try it with Ubuntu though. However now I'm hooked to Procreate and Notability, so I'd end up carrying an iPad anyway. The fully opening bag is only for when I travel on foot. I use hard panniers on the motorcycle, mainly so that I can leave everything on the bike and go on foot as needed. And yes, travelling light is better. I carry everything - gadgets, tools, camping gear, rain gear, 0-to-40-degree clothing, full motorcycle gear - in my two 37L panniers. Again, it means that I can lock everything on the bike and go. It's very important.
