Let the hive mind of Engadget get that for you.
"I'm pretty much a complete noob when it comes to camera stuff. My wife loves to take pictures, though. So much so that she literally wore out her first point and shoot camera, and the Kodak Z712 I bought for her less than two years ago is starting to act up as well. To compound the matter, we are expecting our first born sometime next year. I fear the Kodak just isn't going to cut it any longer. What would be the best starter DSLR to get? She hates missing photo opportunities due to camera 'lag' so speed would definitely be at the top of the list. Photo quality and features would be next. Price should be no more than $800. I'm not interested in video capabilities."
A non-tech-saavy person is a great person for Ubuntu, since they don't have to tinker with anything at all. I'll admit, if something goes wrong or isn't supported, then you may need the terminal and whatnot, but it's almost the same story with windows, except that you have to dig into the registry there. Granted, there are more people to help when you deal with windows problems (not that all of them are really helpful) so that's another challenge, but in 3+ years, the only thing she "broke" was her printer because she didn't use Ubuntu's built-in installer for the drivers on it... she was trying to compile and stuff, according to the Brother website (morons shouldn't be telling the user to do that!). In the end, it was an easy fix when you told Ubuntu to install it... it just worked, and was far easier than Brother's instructions.
