BlueProton via Amazon offers Prime members the Sony Portable Wireless Server, model no. WGC10/N, for $29.95 with free shipping. (Non-Prime members can spend $35 or more to qualify for free shipping; otherwise, shipping adds $8.32.) That's tied with our mention from last fall as the lowest total price we've seen. (It's a current low by $40.) Compatible with iOS and Android devices, it provides extra wireless storage via an SD card (not included).
