The more I tinker with my iPhone, the more I love it. I'm seriously considering getting a 3G (4G when it comes out) iPad. Right now, I'm making this post via the blogger app. I'm thinking if the ease with which I could do this on an iPad with either a wireless keyboard or keyboard dock. I'd be able to take photos and post with ease (like this :D).
It's certainly something to consider. The only draw back is some things I wouldn't be able to do, like edit/upload HTML docs, but I can get around that.
