I've had that happen quite a bit. People are asking me if this could work for them. I think the biggest misconception is that the iPad can work like a computer. I tell them not to expect it to work as a computer. If I could make peace with this onscreen keyboard, I'd find it a lot easier to wait for Apple to address issues like the lack of a filesystem. It's not often I'm the guy with an expensive new gadget and while I don't regret buying the iPad and I do like it, I might opt to take mine back and wait for features to make it work better handling files.
We took a train trio a few years ago and Amtrak rented us a movie player that had dozens of films on the hard drive. We paid the rental and the kids loved it. They especially love watching harry potter three in their compartment that looked not unlike the one in the movie. I thought about buying something similar that would allow them to watch movies on the road but I never imagined paying $500 for such a device. The iPad is more than a movie player but without a credible file system it's not much more than a movie player. I've got a few days left to decide to keep it. I've considered taking it back but I'm leaning toward keeping it. I don't make a particularly enthusiastic iPad ambassador when people see me with it. I don't make those magical comments and I'm up front with them about it's limitations. If people ask me about mine and still want one, they will likely keep it. If they ask a less objective user, they might find they are led to some assumptions that don't pan out.
