I originally got the Verizon 45mm Series 8, but then decided to try the Ultra from Best Buy and am in love with the ultra. I have until October 16th to return the Series 8 to Verizon with the restocking fee, but I have considered keeping the series 8 to wear sometimes as well. What do you all think? Return the series 8 or keep it? I prefer the look of the series 8, but the flat screen and usability/battery life of the ultra. I need to make a decision soon. Thanks in advance.
