What the Arduino?
I enjoy micro controller programming a lot, I've build a couple of devices like a 4x4 LED Matrix. My last project was a joystick controller for my quadrocopter to fly it via an old 4 axis gaming joystick. The Arduino Uno is basically a rapid micro controller prototyping platform. It comes with a USB Interface so you can easily upload your software to it and has a lot of Digital and analog Input and Output pins.
The Arduino Uno makes the step into micro controller programming really easy because it is open source and therefore very well documented. It has a broad palette of software you can load on your Arduino Uno and learn from for your own projects.
I like building stuff with the Arduino Uno, it's really a lot of fun to see your own ideas in action so fast.

Arduino Uno
What is it?
The Arduino Uno is an open-source electronics prototyping platform based on flexible, easy-to-use, highly expandable (you can expand it via different "shields") hardware and software. It's intended for artists, designers, hobbyists, and anyone interested in creating interactive objects or environments with a micro controller.
The Arduino Uno can sense his environment through different sensors and can affect it's surroundings by controlling actuators, motors, lights and many more. You can use the Arduino One as stand alone device or attach it to your computer for communication.
It also has a own programming language called the "Arduino Programming Language" which is quite similar to C/C++. There also are software developing tools for every operating system.
Since the Arduino Uno is open source, you can choose to buy one, build your own or just get a clone.

Start building your ideas today. Micro controller programming can be a lot of fun and is made very easy with the Arduino Uno platform.

But I don't know any electronics!
Fear no more!
This is what I often hear. If you are totally inexperienced with electronics but are still interested in building stuff with an Arduino Uno I highly suggest this set. It has everything you need to start right away, including instructions, a lot of basic electronic components, overlay circuits so you know how to position them on the breadboard, a pinout so you see which pin of the Arduino Uno does what.
It is really well explained and I know a lot of people who started their passion for micro controllers with a set like this.

Build it your self!
for experienced hobbyists
As mentioned above you can build an Arduino Uno on your own, since it is open source hardware. The schematics, Eagle Files, Manual and mounting diagram are all freely available on the Arduino Homepage.But I only recommend this if you are experienced in building electronics since it can get very frustrating in the beginning if you are in a state where you don't know for sure what you are doing.
Arduino Uno Clones
If you want you can check out ebay, they have Arduino Uno Clones there. A couple of months ago I ordered some of those, they work exactly like the original thing and they may (depends, sometimes they are, sometimes they aren't) be a bit cheaper.
If longer waiting times are OK for you (mine came from Hong Kong and I waited 5 weeks) try to get some of those, they also may have cheap peripherals like LCD Displays,...
Since they almost never run under Arduino Uno Clone, try searching for Arduino Uno Compatible, usually you can find some this way.

Reading Material
The Arduino Uno is very well documented. You can find a lot of help online, for example you can find a how to get started for every OS here. There is also a huge Tutorial Area on the Arduino Site. You even have a project list where you can view other peoples projects or add your own.
If you still feel that a book is the better choice, those are the ones I recommend:

Show me an example!
Sure!
So this is the 4x4 LED Matrix I made, actually it is not made with an Arduino Uno, but with a very similar micro controller the Arduino Uno uses. So this can also be done with an Arduino Uno too.
