I've been back and forth on the same subject the last few years. I really like the idea of having a rangefinder and ballistics in my binoculars, but it seems like everything I've found you give some capability within the binoculars, either no wind solutions, poorer ranging capability, less than ideal ballistic solutions, and having a rangefinder within the binoculars (it's actually the LCD readout within the field of view) also diminishes clarity.
I finally landed on running Swaro EL Range TA this last season. The glass is great and the laser and ballistics are ok. I keep them programmed and feel confident out to 500-700ish yards depending on conditions, but I always keep my Revic BR4 rangefinder on hand for anything much longer than 500 yards, or if there are any tricky wind calls needed. Seems to be the best of both worlds. Still have to carry both units, but the binos will handle a lot of the quick/easy/fast scenarios, leaving the BR4 for the heavy hitting.
