Some words to describe the business to aid in logo design: solid, hardened, explosive, lightning-quick, online, thinking outside the box, edgy
You could try all lowercase for the name, i.e. rockbox media inc, if that looks good.  Maybe somehow incorporating a simple lightning bolt or explosion that goes through the 'k' and 'b' in 'Rockbox'...?  Or some other element that shows an edgy corporate identity while still maintaining professionalism?  We're open to anything at this point.
We will be open to working with the winning designer additionally to develop a full corporate identity, including letterhead, business cards, and Web site creation if available.  We will also provide constructive feedback for every entry and will attempt to be as communicative as possible.  Thanks everyone - we're excited about this!
