This deal will be one of several that Microsoft signed with others such as, Panasonic, Sony and Cannon (all Japanese). The motivation for RIMM ( http://us.blackberry.com/ ) is to be able to face Apple and Google squarely in the face and of course it aligns with Microsoft's wish as well. exFAT created for flash drives has better specs than the FAT system (which is not all that fat, could not stiffle the pun) in terms of file sizes (32 exabytes vs 32GB), formatting size, files in a directory limits all eliminated. Vista was not popular but exFAT was made its debut in Vista SP1. You may ask why not NTFS but NTFS has overheads for its special structure not suited for a small footprint. exFAT is not just for Microsoft windows you can use it on MAC as well for models later than with SnowLeopard ( https://discussions.apple.com/thread/2790170?start=0&tstart=0 ) Well, good luck to you RIMM.
