Adobe CEO Bruce Chizen says his company has worked out a coexistence strategy that treats Apple as both friend and foe. “They are clearly both a partner and in some cases a competitor,” Chizen said in an interview with CNET News.com. “They’re an important partner in that about 25 percent of our business comes from people who own Macs. That’s a very loyal customer to Adobe and a very important customer as well. That’s also a very important customer obviously to Apple. So it’s in both of our best interests to partner, and I think we do a pretty good job of it… There are some places where we do compete…in particular in video, and we have agreed to compete. And we compete ferociously.”
