The new blackberry that President Obama is going to be allowed to carry is pretty interesting. One of the more interesting things I found is that the Blackberry cost somewhere around $3,300. That is allot of money for a device, but then again you can not really put a price on security. The new device will probably take a little while to get used to since it is not a traditional blackberry. The below links have in depth information on the new device for the president.
