I have seen one guy using a Surface Pro at the Mall of America... And that's it. I have yet to see an RT apart from my own. But it's kinda cool having a device that not many people have as I get asked about it all the time.
Yeah, if Windows Phone and Surface ever actually gain significant market share, I will actually be almost disappointed. While it bothers me how everyone hates on WP and Surface/Windows 8, often without much justification, and more apps would be nice, I also kinda like going against the grindstone.
Wielding my Nokia, everywhere I go I'm unique. Even though my Lumia 1020 is black, it still manages to stick out amongst a sea of iPhones and Androids. I love it when people come up to me and ask about it. It's awesome, I love to stick to the shadows, yet standout at the same time.
So while more market share for Microsoft would be nice, it'd also be a real shame to lose the uniqueness that currently comes with being an early adopter.
