"Onda V989 (with Allwinner A80 Octa-core ARM Cortex-A15/A7): $180 Onda V989 Air (with Allwinner A83T Octa-core ARM Cortex-A7): $130 The A83T is a bunch cheaper than the A80, too bad I think Onda didn't name the A83T version more differently, it's confusing the consumer I think, the difference in naming is just the " Air" part." - Charbax
