What makes you think they're focused on businesses? I've always thought it was the opposite. You make a pastel-colored website with super-simple file-sharing software because you want to attract individual users. If anything, I'd think businesses would find Dropbox irritating, because it makes it easy for their employees to leak documents, intentionally or otherwise. It's simple enough to setup a corporate file server for file-sharing needs.
