I didn't mean comfort (although I suspect that it may come into it more than you give credit for).

I meant hassle; effort - should I just scribble notes, or will I spend a couple of minutes thinking about what info I want to record before I see it on screen? I could knock up a quick spreadsheet of the relevant comparison points pretty quickly, but I wouldn't bother if there was a pen and paper in sight. If I already had a spreadsheet that I'd used previously, though, I'd use it again. I'd use the website in question if it was equivalent to that, and free. (Sorry OP, I can't think of anything you could add that would make it worth coughing up for, for me at least.)

It's fickle, sure, and it's a very minor difference in effort. That's what people do when they're not really giving much thought to what they're doing, IMHO and IMHE.
