6a)For each of the property the information returned wasn't the same. Web browser version
and User Agent had a little more information added to it.It was accurate still but with more stuff added to it.
6b) I only have Google Chrome and Internet Explorer, I can say that Web Browser version
and User Agent properties were different. They look one way on Google Chrome and another way
on Internet Explorer. On Internet Explorer it has added stuff to it such as "WOW64; Trident/7.0; Touch;"
versus on Google Chrome where it doesn't have that.Web browser and Operating platform stayed the same.
6c) The challenges I see is that you might not have a certain browser on your computer. If you have
a window computer, the Apple app's that are open for the browsers might not be for you and vice versa.
I think Web browser version property and Operating platform is the most useful because you can see
what new browsers is out there and what platform your computer has.
