I don't get it. Why some people treat a phone as a investment instead of a tool?? I am not rich. But I care only what a tool (or phone) can do to me, not the rate of price drop (why not buy it later if you really care for lower price?).
For X1, you saw a lot of sellers because many WM newbies brought the phone by the look, and sell it after they found WM is not their cup of tea. That's why I only recommend X1 if the original poster is comfortable with WM. After all, X1 is a excellent WM phone but may not be everyone's phone.
