I don't want to carry around 2-3 devises.
BES doesn't store personal email (I assume you mean mail via BIS) however, a BES admin pretty much has full control over and pretty much complete access to a Blackberry connected to the company BES. That means that your two requirements above directly conflict with each other.
If privacy matters, you'll have to carry two Blackberries. If privacy doesn't matter and
corporate IT policy allows use of BIS you can carry just one.
