This week's most amazing blog item, about a Finnish software developer who lost his finger in a motorcycle accident and replaced it with a prosthetic USB drive, just scratched the surface.

Jerry Jalava's sci-fi finger became a Web sensation after a friend of his blogged about the creation, noting that the drive was loaded with a version of Linux.

Jalava clarified the situation on his blog last night. For one thing, it's not permanent. For another, it's loaded with more than just the Billix version of Linux.

First of all it is not attached permanently in to my body, it is removable prosthetic which has USB memorystick inside it.

Secondly when I'm using the USB, I just leave my finger inside the slot and pick it up after I'm ready.

Currently I have Billix, CouchDBX and Ajatus installed inside it.
I'm planning to use the other prosthetic as a shell for the next version, which will have removable fingertip and RFID tag.

Separately, on his startling Flickr page, he answered the capacity question: His finger holds 2 gigabytes.

Here's a screen grab of the page:
