I try to be open to changing my mind when better evidence or arguments come along. I think I'm the only one in the history of the Internet who ever ended an online debate by typing, "I hadn't thought about it like that, you're right."
On some topics, my opinion lies so far outside the mainstream that I think there's a fair chance it's incorrect. When I notice, I try to make a good-faith effort to figure out what I'm missing. Sometimes I come around, sometimes I don't. I've come around on the artist Marc Chagall: I never liked his work until I went out of my way to study it; I still wouldn't necessarily want it hanging on my wall but I do genuinely appreciate it now. On the other hand, I still haven't come around on guacamole: nearly everyone I know loves it and I don't. People tell me, "Oh, you just haven't tried mine!" so I always do, hoping that this time I'll crack the code, but it's all flavorless green phlegm to me. Still, I try it every time.

I don't get it.
I considered buying an iPad shortly after they came out, went down to the Apple store, got the sales pitch and demo, and stood there staring blankly. I couldn't imagine what I would ever use it for. Nothing it did was anything I'd ever want or need to do. After my wife Karen recently got an iPad 2 for her job, I eagerly sat down to play with a fresh attitude, poised to be persuaded. Five minutes later I was bored and done (and I spent half that time taking pictures of my cats).

I ask people who have iPads how they use them. They say, "Web browsing," "e-mail" and "apps." I do the first two while working at my computer all day; when I'm away from the computer, I don't want to do them anymore. That's my "don't do anything remotely computery" time. E-mail can wait a few hours. As for the apps, I dunno. I realize there are hundreds of thousands and I've test-driven maybe half a dozen, but they were not compelling toys and certainly not worth the $500 it'd cost to get started. In addition, I'm not very impressed with the iPad's vaunted design. It's not as intuitive as advertised. When I have to double-click the button and swoosh my finger to make something happen (but not swoosh too hard or something else will happen!), I think it'd just be polite to explain that.
I can read your mind: I'm a cranky fossil who just doesn't get it. Trust me, I sincerely want to. It's pointless to argue with me that I'm wrong, I admitted that in the post's title. My mind is as open as I can pry it, ready to be seduced. So far, the iPad hasn't even cast me a flirty glance from across the room.
But I might be wrong.
