Concerning SLR Cameras Nikon and Canon are both very good. I find that Canons have a faster Autofocus, generally are lighter and have nicer/more intuitive setups. On the other hand Nikon's tend to be a bit meatier and have those awesome Nikon lenses. I started with a Nikon F50, which is a good basic (picture driven) camera. This is a good beginners camera, but becomes frustrating as you want to take more control of the shooting process. My next camera was an F70, which was great, but had a really aweful button driven setup. I am now using an F90X and this baby rox (although it isnt cheap). I'm sure all these models have been discontinued by now, but when i look at the newer, cheaper Nikon cameras, i am generally more impressed by Canon, if you want to pay a little more i endorse Nikon all the way.
Where i live, second hand Canon Leneses tend to be a fair bit cheaper, which can be important if you are wishing to get into photography bigtime. Pentax is another really good and underrated brand.
Looking at your initial pic, it seems you are more interested in a non SLR camera. In this regard Olympus are as good as any other brand. I am not too up with the models anymore, but the mju series of Olympus cameras were very very good.
Whatever you do, make sure you get to have a play with the camera for a while.
PS Hasselblads make me drool too
