Ask HN: should I buy this company?

I have a friend who's been running this business for a while and has finished the technology and found a small user base. However, he's considering selling it and I'm wondering if people think there is a worthwhile space to pursue for these devices in the market place. IMO the business has a medium-level technology moat but it has a pretty impressive UI compared to alternatives.

Some ideas on where to take the business are:

- Selling/leasing to a national office supply chain for resell to small businesses - Selling to music concerts (get a USB key of the concert as you walk out) - Manufacturing (Apple's new Air USB key is kind of a hopeful sign that we're transitioning past the age of CD).

Any thoughts by people in this space or even if you can consider a use-case I'm ignoring would be greatly appreciated.
