To those of us that know Photoshop really well, the process is more advanced than what the author suggests. For me, Photoshop is equivalent to pencil and paper -- I can see where things ought to be, how they actually might look on screen, and whether or not it is visually appealing.

I don't fault the author for having his own process, as it seems to be working for him, but having never done it the other way, I can't imagine how he can condemn it. The argument seems, at a glance, akin to a lifelong vegetarian railing against steak.

I don't work too dissimilarly, in that I will start a layout in Photoshop, start coding, then drop back into Photoshop when I need a new visual element, but when I need to plop a logo or button onto the page, I generally have it at least roughed out in Photoshop. My process works for me, generally, and I've done it both ways, but without prototyping the page in some way, I have a harder time envisioning what to code.
