OK, I'll throw my $0.02 worth into this discussion. As a long time Minolta owner (bought my first Minolta 35mm SLR in 1985, and currently own a Sony Alpha, which is essentially a Konica/Minolta camera) Here is how I see things when it comes to decent cameras:
If you have deep pockets, get a Nikon. They cost a lot more, but they are virtually indestructable (that's why a lot of news photogs use them, and they are pretty much "standard issue" for US military photogs). They take very good pics, and give you "pro-level" control over functionality. But if you'r enot a hard-core shutterbug, you may have a hard time getting pro-quality results" from a Nikon--they can be a little TOO dependant on the user's skills...
If you want a camera that is REALLY easy to use, but maybe not "battlefield rugged", and you're probably going to replace it in 3-5 years anyway, get a Canon. They take good pics, are very easy to learn and use, and in skilled hands can yield impressive results.
If you want to get the best bang for the buck--durability approaching Nikon, higher resolution than either Canon or Nikon, and a wide range of controls ranging from full-auto idiot-proof to full-manual arsty-fartsy, get a Sony Alpha. They are based on the Konica/Minolta cameras, and at their price point, the other two brands can't even touch it. But The Sony SLR is sort of like Martin Logan speakers--they put you in a sort of "outcast club" among some of the snootier camera buffs (mostly because your camera will have 15% more resolution at 1/2 the price, I think...) And also, all the old Minolta Maxxum lenses are 100% compatible with the Sony Alpha, so you can get used lenses to go with it for REAL cheap. The Sony Alpha is not the BEST camera out there, but it is a "giant killer" at it's price point. It's sort of like the Benchmark DAC of the camera world--sure it's not a Wadia, but it's REALLY damn close, and at 1/2 (or less) the price...
If I had unlimited funds to spend on my camera, I'd either have a Nikon or a Pentax 645 (with a digital back). But I don't, so I went with the camera I've known and loved for 20 years. My Minolta's never let me down (Maxxum 5000, 7000, 9000, several lenses, flashes, remotes, Cokin filters), so I went with the Sony Alpha when I went for a Digital SLR, and I LOVE it.
Of course, YMMV...
