I recently picked up a black 928 to replace my red 8x (Verizon). I had the 8x since the day the red one was released so I'm pretty familiar with Windows Phone 8 but am excited to learn more about the Nokia exclusive stuff! Only drawback I've experienced so far is that 2 of the apps I had on my 8x are no longer available in the marketplace and I can't get them on my new 928.
