You have access to desktop applications, including the possibility of custom apps created using Visual Studio or other well-established tools, and deployed without the hassle of app stores or developer settings.
The Windows operating system is more powerful but less secure, and a few false taps on an email attachment or malicious web site can compromise the device.
IMO a six year old will click on anything that promises them a lollipop/pony etc.
My guess is that your network will be hacked in no time at all. As the bad guys will know your flight dates you can expect to be burgled as well.
