( Mobile ) - USB Flash drives are great because they're so compact, yet they can handle a fair bit of data. A rather major shortcoming of most thumb drives, however, is that you really have no idea how much space you have left without plugging it into a computer. Not this drive, however.
The Corsair Readout USB 2.0 Flash Drive boasts a built-in display with a pie chart representing how much capacity is being used and how much more is still available. You'll also notice that it can show the label you've assigned, so it's easy to differentiate between the dozens of flash drives you have kicking around the office. The screen is an energy efficient Bi-stable Cholesteric Display (BCD). No battery needed.
Looks pretty sweet, but it's a touch on the chunky side, wouldn't you say?
