I'd interpret it roughly as "If your product looked/acted a little different we'd us it."

Ask them what they mean. Seems straight-forward. If it isn't, they're just letting you down nicely, if confusingly.

(FWIW, communication like this can be used both as a conversation starter, or killer. It's frustrating--people should just say what they mean. In fairness, they may not know what they mean, which gives you a potential opportunity.)
