Really though BB is a great business phone. Android and iOS will soon catch up to it eventually as everyone seems to be making the switch. For now I would say the D3 would make a great business phone. Has a nice keyboard for typing those lengthy or multiple emails, nice speed thanks to the dual-core processor, and great build quality imo. If you want to wait the D4 looks to improve in all those areas and with 4g LTE, so you'll be blazing through your work e-mails in no time.
One plus is if the OP does have an OG DROID. The battery in both the Pro and OG are the same. So out of the box you have two batteries.
Outside of that. I believe any business features the pro has is in all current Moto phones on verizon.
