Amazon is offering the Kingston Wi-Drive 64 GB USB 2.0 Pocket-sized Portable Storage (WID/64GB-A) for just $71 with free shipping. That is a total savings of $59 off the average street price of roughly $130 that major retailers like Newegg and Adorama charge. The Wi-Drive provides an additional 64GB of media storage, via 802.11n connectivity, for an iPhone, iPod touch, iPad or any device. It can be shared with up to two devices at once. Apple doesn’t let users add on-board storage to iDevices, the Wi-Drive is your best option to make room for those bulky Retina apps and HD videos. After you buy the Wi-Drive be sure to download the iOS app.
