Shame, really. By concentrating on the enterprise market, Box may have sealed a brighter future for themselves than Dropbox has. That's sad because I'm pretty sure the team at Dropbox could run circles around the Box team. I mean, they have Python's creator working for them.
And there's a lesson there for would-be entrepreneurs with a technical background - your technical abilities only play a small role in the success of your venture. The smart business move is to focus on generating revenue, like Box did.
