Stunning little device - not quite as amazing as 16Gb on an SDHC card, but pretty close. (Some of us remember IBM PCs with 5Mb "Winchester" drives, about twice the size of a modern CD/DVD drive)
Copying files between this and my Acer Timeline 4810T-353, it took around 30 secs to copy 100Mb from the PC to the flash drive, and about 20 secs to delete the same set of files on the flash drive. Copying from fash drive to PC was about 7 secs. When there's activity on the drive, a little green light flashes, under the "flat-top man" logo which you can just see on the product picture.
Not concerned about lack of protection for the USB plug - it will be used in as clean an environment as my iPod lead, whose USB plug has been unprotected for 2 years.
Stores over 2000 JPEG images from a 12 Megapixel camera, so the ideal last line of defence against losing our holiday photos, already stored on laptop hard drive.
