I'm researching DSLRs for an upcoming purchase, and my budget will be around $1k for a camera body and kit lens. One area where it's difficult to find information: How do I learn more about the OS's user interface? The person I'm buying for is an experienced photographer who's found herself without a camera for several years, and will definitely appreciate a camera with a good OS.
There are, of course, many other calls I have to make, such as lens availability, but what brands of SLR come with a reliable, well-designed OS with a good software UI? I'm talking about the built-in camera software, not the bundled software for your computer.
Edit: A "good" UI, to my way of thinking, is one that's consistent, and one that, once you learn a few basic concepts, is easy to learn. Eye candy is also nice (as in OSX), but not necessary. Perhaps what I need to do at this stage is eliminate camera brands that use very bad UIs.
