Hope this isn't a new trend:

Keane are set to release a limited edition of 'Nothing In My Way', their third single taken from 'Under The Iron Sea', on a ground breaking new single, the USB Memory Stick (Mac and PC compatible).
The 512MB USB memory stick contains audio and video versions of 'Nothing In My Way', three animated screen savers and a link to view an alternative video.
Only 1500 will be produced for fans, and they will solely be available through HMV.co.uk and HMV stores around the UK.

I see it's also on CDS and 7", anyways here is the link:

It's already sold out.

if you can rewrite the stick, that's a whale of a deal.
