Not true at all. Microsoft's System Center Mobile Device manager does everything you listed. You could argue that the BES does it better or that the BB devices are superior to Windows Mobile devices but the fact remains the same ability to control and lock down devices as well as provide behind the firewall access is there. That said, I would say the majority of corporations using smartphones are doing so purely for email and have no desire to provide behind the firewall access nor want to lock down devices to the extent where the camera is disabled. In those cases, the company is crazy to spend the money deploying BES when any device that supports activesync can be used natively with Exchange without the need for any addidtional hardware or software.You can even use BB devices with third party software on the device that adds activesync support for a whole lot less than deploying BES.

Once the auction ends, a binding sales agreement has ben formed, under contract law. Once bidding starts, the auction cannot be stopped and the item must be sold to the highest bidder, unless a reserve has been specified before the auction begins. Bids may be retracted before the sale is complete, but once the auctioneer announces that the item has been sold, the highest un-retracted bid is binding.
