An apple camera would be great because lets face it the industrial design and interfaces of most cameras can be a bit of a mess, and quite confusing if you aren't too knowledgeable about all the terms. Imagine what Apple could do to make an SLR for the rest of us that made it easy and simple to take great photos and teaches you to operate the manual controls and get better.
DSLR are for prosumers/professional users. I see so many people having a DSLR and they don't know how to use it (you know, they just shoot in "green square mode". So stupid, just get a point and shoot if you don't know what the options mean. If you don't know it, you don't need it.
