What Would be a Suitable Camera for Me?

What are some really good cameras? I am an aspiring photographer, but I have your run-in-the-mill crappy camera. Next summer, I will be taking a school trip to Dublin, London, and Paris. I want a great quality camera for my trip but don't know where to look.
This is my ideal camera:

Is that a good camera? Or do you think I should get a different one?

Which camera would be my best choice?

I'm under a budget because I have to save for the camera by myself and i'm not really patient. Oh, i'm not an avid photographer, just some simple photography like sunsets, flowers, etc.

The four cameras that caught my eye are;

Canon PowerShot XS500
Olympus E-420
Nikon Coolpix P510
Nikon D3000

Need a good first camera?

So i've been thinking of getting a camera. I don't know the type of things that professionals would know about cameras this is basically my first camera. I'm 17, still in h.s and this is just basically a hobby for me. Any suggestions for a first camera for the people who know more than i do? Price range somewhere from 250 or 300-400, i'm currently planning to get the Nikon p510.

What camera should I go with? canon SX50 or nikon p510?

Hi, I'm getting myself into digital photography as a serious hobby, I really get a kick out of it. That's why I need a versatile camera to get used to everything and work with it as much as possible for all sorts of situations (landscape, portrait, macro, wildlife) and get a feel for manual controls over time, but I don't want to dish out huge sums of money on lenses, that's why I'm going superzoom/bridge route in stead of dSLR route.

My two choices right now, also available in my country, are the nikon P510 and canon SX50.

But I'm having a very hard time deciding which to go for. I think technically the SX50 is better, but for some reason, looking through tons of samples I can clearly tell the difference between pictures taken from the p510 and those taken by the SX50 and for some reason, I just "feel" those are better looking pictures, maybe I'm crazy.

Any opinion is greatly appreciated.

Does anyone know how to hack a Nikon Coolpix P1?

I want to be able to take time-lapse photos with an interval less than 30s (10-15s would be perfect). Does anyone know how I can do that with a Nikon Coolpix P1?

Thanks!
Added (1). Would I be able to change the interval time to the exact time I want if I were to hack a canon?
