Choosing a camera for life?

I've studied photography for a long time with everyday work and kids i just lost track of time and now i want to explore my passion once again. But i'm confused which camera to choose from? As i'm not interested in the HD feature (movie option) i'm more interested in stills, landscapes, and night scenes! Canon 60D, Canon Eos 550D, Nikon D7000 please suggest. Yes i know all three of them have movie option but do suggest if you know a better choice. Budget is not an issue so far…

I would recommend either the T2i or D5100 so you have more money to put towards nice lenses. For landscapes - Canon 10-22 or Nikkor 10-24. Portraits - 50 or 85. Low light - 50 or 35.

I like my Nikon D200, and have been using the first gen 18-200mmG VR for the past 5 years. One lens does it all. It's heavy (magnesium body, no silly plastic), dedicated WB, ISO, and Qual buttons, and will use almost every lens Nikon has made since like 1959. Works for me.

Nikon D7000 or pentax K-5

I've seen no evidence yet that digital cameras, no matter what cost, are expected to be still functional in ten years time. On these pages you can read about digital cameras less then two years old that are complete failures.
If you want a camera to last a lifetime I suggest you buy a quality film camera and lots of film. Keep the film in a fridge and lok after the camera. I still use near 80 year old Kodak Retinas and a mid 30's Zeiss Super Nettel for 35mm work. For more demanding stuff, my Pentax/Praktica SLRs are all 35 years or older. I love using, for really special stuff, pre-WW2 Rolleiflexes or Zeiss Super Ikontas. If you've learned to drive then using cameras like these is a breeze. Plus, being very collectable, they cost nothing to own.

Leica M9, its an investment for life

You mean you want to marry your camera?
I have a Canon 60D, upgrading from Canon 400D (which lasts 3 years).
I think it can be a camera for life, but, it might not last more than 5 years.
You know, things break, especially electronics.
If you want a camera for life, seriously, then you can get a second hand hasselblad or leica, with negative films.
You mentioned you want to shoot night scenes? I think any DSLR can do decent night scenes. With a tripod and a table lamp/a LED, you can shoot anytime anywhere. If you are interested, you can check out a short clip I just uploaded, shooting night scenes in movie mode with my Canon 60D.

I use a Nikon D70 which as been out 8 years now and still going strong, and I don't baby my camera.
