With 4GB of onboard memory, and a 4.3" screen, it seems to me like ZTE have made a very mismatched device. All handsets should really have a minimum of 8GB, wpcentral reported the cost of 16GB found in the 900 was $27.00, so the difference for 8GB vs 4GB would probably be negligible. Nobody would want a WP device with 4GB imho, no matter screen-size, unless it was priced sub-?130 (which is precisely where you can buy the 710 atm).
