I guess I'm just trying to justify a gadget I'd really like to have for no good reason.
Even now, I don't do much iPhoning on the go. If someone else is with me, I have
them do the imdb-ing, the mapping, the restaurant-finding, etc. (Part of that is, now that they've invented the iPhone, eye don't have the i's for it. The bigger iPad screen would work so much better for me, but it just won't fit in the pocket of my tight jeans.)
I'm rarely alone and outside of work or home, where I might want to amuse myself or do something useful with a portable computer/internet accesser. I kill maybe 10 minutes a day aggregate on facebook or twitter on the go, and that's the extent of it. The iPhone is perfect for that. I already have one.
But, damn, I want an iPad. Don't have a single use for it, but want it. That, my friends, is marketing success!
