I saw a man and his wife both with windows phones at work the other day. I noticed the wife's phone first, as the yellow 1020 caught my eye immediately. Then noticed the man had an 830. So a approached the couple and said "ahhh, the Nokia 1020! Awesome phone, and an awesome camera!" As I pulled out my 1520 to engage in a windows phone conversation. The guy says "yeah, I'm running windows 10 on mine." "oh" I replied, "so you're a Windows insider as well eh?" "Well, no, I'm a Microsoft employee" he says, fondling his phone. "They just sent me this one" he adds. "the 830 right" I ask, trying to impress this MS employee with my phone knowledge, "No, this one hasn't been released yet" he says. "it's a prototype". So, knowing that his phone was definitely an 830, I ask him what phone it was. He starts looking at it all around, popping the cover off and reading the numbers "I really don't know, but I know it hasn't been released yet"
Clearly this MS employee has no clue! Imagine that...
