Off the topic perhaps, but I remember my first photographic trip and there were all these people in a place they had never been to and will probably never go to again, sitting in a hotel room editing photos.
I now ditch the computer, take lots of cards and spend my time photographing the sites and absorbing the culture. The shots are right when I click the button and they will be right when I sit in a comfy chair with a big monitor and powerful computer back home.
I know exactly what you mean, but it's not necessarily computers to blame. My girlfriend was on a business trip to China a few years back and all the chaps wanted to do was sit in the bar and drink as opposed to having a look around Shanghai.
I will download, sort, name + backup photos out each day whilst away, because if I wait to get home to do that, I may have forgotten the names, details etc that are needed for organising. And that's tediously time consuming when somewhere new and interesting. Though I may grab a shot that catches my eye to post on FB, but that's so quick compared to filing, it's no big deal.
