If you had any lingering notions that Apple and IBM were still bitter arch-rivals, they just got swept away. The two companies have just launched a partnership that could give iPads and iPhones a much larger presence in the workaday world. IBM has agreed to develop over 100 enterprise-grade apps solely for iOS, along with iOS-focused cloud services; it will also sell Apples mobile gear as part of its larger solutions, and its even handling on-site support.
