Hello, If the iPad Pro 10.5 were your main device, which phone would you get to use as an accessory to the iPad to use when you were out an about? For example, I like mountain biking and canoes/kayaks/small sailboats. I have seen some waterproof cases for iPhones. These are places that I would not take the iPad Pro, but I would like to remain connected with my family, and take some photos to send to the Ipad for editing/viewing/storage. The iPad Pro has LTE. Thanks in advance for your input.
