This reminds me of funny story back in WP 7.5 days.My friend bought himself a Samsung Omnia W (or Focus S as some call it) .
He sat at his desk in his office and unlocked his device and started scrolling up and down the Tiles screen. I had to answer a call for a few mins and when I came back I went by his desk and he was still scrolling up and down aimlessly. I mean for 3 or 4 mins that's all he did, we laughed our asses of.
He later told me he was very new to Windows Phone (he was a feature phone user back then) and admired the tiles,smoothness and color of WP and hence the funny situation. During late 2011 Windows Phone was something uber cool, now it is a commonplace. I am really happy to actually be there to see Windows Phone grow, albeit still 3 years old.
