Actually, I think BIS is pretty good. It works as it is designed to work, with no interaction required of the user except for setting up your accounts initially. I have never needed to have email in real time, and I have been the CEO of two companies and senior VP at two others.
If you need it instantly, you can look into a hosted BES solution from exchangemymail, mailstreet or other similar providers.
