the iPad simply falls into the market for gizmos-with-bitten-apple-logos-as-status-symbols.
I'm going to be a teacher, and there are so many uses for this thing in my mind that I will be crushed if they aren't implemented into an app. Start with ibooks. I'm tired of the cluster of kids I see trying to get out their textbooks and turn to the right page, can you imagine what this thing is going to do for my sanity once textbook publishers get stuff out on this thing? Next, I send them a worksheet through some app wirelessly that they have to finish, bam, they flick it back to me. I can't stand paper, paper is stupid. I want my job to be paperless. Then hook this baby up to my smartboard so I don't have to try to write with those Fake Sugar Dick (WARNING, NOT THE REAL SUGAR DICK!) markers. I'll stop there, I could go on and on
but, you say there's not a market for this, I say stfu and go check out the madness in a classroom.
