As much as I like to make fun of Apple products, anyone relying on an iPad for navigational purposes was just asking for something like this to happen. I do feel bad for the ferry that was minding its own business when this guy crashed into it though.
The iPad is undoubtedly a versatile device, but there's no getting around the fact that Apple's tablet has its fair share of limitations. A few months back, a U.K. sailor named David Carlin learned this the hard way after deciding it might be a good idea to navigate a 50-foot World War II boat he was steering via his trusty iPad.
