As an aside, why does the auto-answer feature only work "out of holster"?
Becasue RIM is protecting you from you! :P
A bluetooth headset will allow you to answer the phone at the touch of a button on the headset itself. Might be a cool option. I'm using a TREO side case right now so my 7100 is out of the holster even when it's in if you catch my drift.
