Kingston 32GB wireless iPad/iPhone hard drive: $100 at Amazon
You can load up Kingston’s 32-gigabyte Wi-Drive with music, photos and movies, then wirelessly stream them to nearby iPads and iPhones. The drive’s built-in Wi-Fi connection can be shared with three people at the same time, which makes it a good option for keeping the kids entertained on a road trip—or if you don’t have kids, keeping your friends from complaining about their jobs, apartments and love interests while you’re driving.
The same drive sells for around $130 elsewhere—even the 16-gigabyte version also sells for $100 at Amazon.
