The Jumpdrive Mercury from Lexar is one of the first usb flash drives to incorporate eink technology – the drive has a handy eink display to show capacity used and how much is remaining. Okay so it may not be the most interesting eink product ever but it is handy functionality to have.

The high contrast display has a 10 bar capacity meter that, like all eink products has high contrastand low power consumption. The capacity used and remaining is shown in percentages.

The Jumpdrive is available in 1GB and 2 GB formats and at only $10 more than an equivelant drive I’m sure it will prove a useful product.
