IronKey has sold its USB-based security hardware business to Imation. So I predict that quality will plummet and price will increase. They are honestly way overpriced as is...

I'd rather stick to truecrypt, I control it, I set encryption lvls, key strengths, cypher types, container size/s. It is transparent, unless you know what you are looking for you'd never something was "truecrypt'd"
Security threw obscurity is still a good practice.
