I never ordered an 8700 charger. I've had my 8700 for about a month now, and have been exclusively using my 7280 accessories - wall and car chargers. Everyrthing works great. This is a USB device, so I wouldn't expect things to be otherwise. In fact, so long as the device plug is mini-USB, I don't see any reason that one couldn't use the 7200 Blackberry chargers to recharge any other USB device, be it a camera, a navigation system, or a Tickle-Me-Elmo running Linux. As far as the .75A on the 8700 charger, all it means is that it might charge the 8700 faster than the .5A charger. If anything, the danger lies is using the 8700 charger on 7200 Blackberries.
