It might just be that I'm out of the loop, but this is the first time I've seen a flash drive with an integrated MicroUSB connector (and regular USB for PC), eliminating the need for a cable adapter to connect to phones/tablets. At $24.99 after MIR for a 64GB USB 3.0 Patriot drive (I've had good success with Patriot before), this looks to be a heck of a deal. Note that the default shipping option that comes up is $5.99, but a free shipping option is available.
