I thought the author was trying to be fair in the sense that he emphasized that most of what he was saying applied specifically to him, and maybe not to others. I do think that most of his objections would have vanished if he were more familiar with Photoshop, and if he'd worked out a more rigorous "save" routine in the evening. I used a Flashtrax for a while, and it took about 17 minutes to download a full 1G card, but I didn't sit there and stare at the machine while it was downloading. I did other stuff, so I hardly noticed; you could do it while you were driving back to the motel...
But his essential argument is one that large-format photographers have made for years, that is, that the awkwardness of the (film) technology is a positive benefit, because it imposes a form of discipline on you. As somebody else noted, though, it's not the marginal photograph's fault that you spend an hour trying to improve it, when, if it were on film, you would have discarded it immediately...
I think he also glossed over some aspects of the problems of shooting outdoors. Most of my hard photography I do on a archaeological dig in Israel, under pretty bad conditions (dust, heat, harsh light modified by deep holes, etc.) The essential problem is that after an archaeological feature is recorded, it is destroyed -- you continue digging down through it, or, if it's an artifact, you remove it so you can continue working. You can't come back for another shot. When we shot film, which we no longer do, I always worried that something was going to get messed up -- the processing, or that I'd gotten the exposure terribly wrong, or that something had gone wrong with the camera. We did actually have a roll of transparency film developed as color negative, which didn't do it any good. (We had a backup.) With digital, we can immediately confirm that we have the shot. In fact, we can confirm that we have it on both cameras, so there are always two versions on different machines. This, for me, is huge. I would think the same thing would apply to a wildlife photographer or a landscape guy, that the benefits are so wildly in favor of digital that the other considerations would fade away. (And I shot film for 40 years...)
