Beijing-based Android handset developer Xiaomi held an open preordering event for 150,000 of its Xiaomi handsets today. Pre-ordering was open for only 20 minutes before all 150,000 handsets were sold out. Customers were limited to one handset per person. In the latest round of pre-orders, customers were asked to place their order before paying to purchase the handset. Handsets will begin shipping in one to three weeks' time, and will all be shipped out within a single two-week period.
