I really like my iPad. I do worry that I will drop it and crush the screen sometime, but that worry isn't strong enough for me to wear something like this new iPad holder called the Assero Defender. It looks like one of those baby carriers that some people carry infants around in.
This contraption is sort of like a backpack that you can wear on your chest. It has a flip down flap that the iPad is mounted on that you can unzip for access to your iPad while standing without having to hold the iPad.
The downside is that this is one of the geekiest (and not in a good way) things I have ever seen. It will also cost you $130 despite the fact that it makes you look like a real ass-ero.
