Carting a large sized USB drive around is handy but Kingston has gone one step further with the MobileLite Wireless device which acts as a WiFi router for an attached USB drive or SD card.  It sports a 1800mAh 3.7v battery which should allow for up to 5 hours of usage and up to 3 devices can connect at any time making it a nice WAP you can carry around with you.  By not including any storage media Kingston kept the price down and with SD support you can store quite a bit in the device as long as you purchased a large SD card. The transfer rates that HiTech Legion were seeing were not incredible but would suffice for streaming video and certainly data.

"Kingston MobileLite Wireless is a flexible Wi-Fi storage device that is lightweight and portable. The MobileLite Wireless acts as a USB hub and a card reader when plugged in to a laptop or a desktop computer. When unplugged, the MobileLite Wireless can then be used as a wireless file server, allowing up to three simultaneous wireless device connections to access the data stored on both the USB port or the SD card reader slot when populated."
