Hello to all. I just purchase an X Pure from Best Buy and was able to pick it up new at $225. Is this a good buy do you guys think? Also can the back shell color be changed out? Lastly anyone have any advice on the Pure you could throw my way. I'd greatly appreciate it. Doesn't seem like 5.7 inches. Am I correct on the screen size? So far I'm just updating it and haven't had a chance to dig into it yet. Any advice would be appreciated!
