So I've been a Windows guy since 1991... but I have both computers on my desk to support work stuff. Windows 10 is amazing as is the Surface line of products. But for a phone I can't get away from the iPhone. not just for all the investment I've made in itunes products etc, it's just the best platform for security (device encryption) and it has the best app store selection.
I've specifically tried to stay away from an iPad, not because they're bad devices, but I could see myself zoning out on the iPad way too easily. I try to only use my laptop when I have real 'things' to do, photos to organize or paperwork to do or something.
