I've used a couple other microcontrollers (pic, picAXE, and messed with a few others) and this is by far my favorite. It is programmed over USB, so it is very easy to set up. There is software available for windows, OS X, and linux. It supports hardware serial communication with a UART (don't worry if you don't know what these mean). The programming language is the absolute best microcontroller language out there, a mixture of processing and wiring. Processing is a language based off of and very similar to c++ (when I started with arduino, the only experience I had with the language was previous casual use of c++). Wiring makes it very easy to use, with low to high level features, which means that a beginner can easily do simple things like blink an LED with just a few lines of code, or do very powerful things like "bit-bang" serial communications at a hardware level or actively modify the program memory. The chip also has built in EEPROM so that you can store data easily after the chip loses power (like if you turn it off). If you are good with computers, you can even make your own firmware and upload that (I won't get in to that). The great thing is, if you need to embed your arduino project you can pick up an ATMega chip and a 16mhz crystal for just a few bucks, and then upload your code to the ATMega over "avrISP" (a program included with the free arduino software) without spending any extra cash. This board is great for experts and beginners alike. It took me, a complete microcontroller novice, about 2 days to become good enough with the language to make usefull programs (like home automation) and now a few months later I can do some really crazy stuff like overlay text to video, or interface with electronic devices like GPS units or phones in ways I never would have been able to before. The arduino also has a huge and experienced userbase. This means a huge and helpful forum, not to mention LOTS of documentation and software libraries that let you use the arduino with GPS, phones, touch screens, LCDs, memory cards, video modifying chips, sound chips, the internet, wireless communications, and much more. A simple google search will probably turn up how to use something with an arduino. I say buy it! By the way, this is far from a toy. It's a powerful tool.

This is a great little microprocessor board. I would rate this toy as not durable, except the 1 start rating corresponds to "I hate it". I don't hate it, its an exposed microcontroller board with leads coming out of it! I really need more time to use it, but once you get it working right (like checking the right COM port), its pretty cool what you can do with it!

Easier to program than a Xilinx IC chip!
I'm an EE student and I picked up one of these to tinker. I bought one of these with a motion detector sensor and within twenty minutes and two google searches, I had a working prototype built. It helps to have at least a semester of circuit theory and a small geek box of resistors if you'd like to build anything. It's a great device for knocking out quick sensor and controller projects!

The Arduino Duemilanove is micro-controller programming at its best. The Arduino series can't be beat. And this one is their newest model. Arduino is versatile and can do nearly anything you can think of. Their website is full of support and tutorials. Best open source micro-controller out there.

If you need to automate anything - make something happen based on some sort of sensor - the Arduino can probably do it easily, and cheaper than almost anything else. It's is a terrific platform for electronic and robotic projects, and any project that needs some kind of automation. I'm a high school Physics teacher, and my seniors put together some incredible projects for class with only two weeks or so of programming and circuit-building instruction: light-sensing robots, model elevators with call-buttons, vending machines, a motorized car-wash, even a Pong game. In my after-school club, sophomores and juniors have also taken a real interest in it, though they need a bit more direction. I don't think it's appropriate to call this a toy, because typically you'd have to be high-school age or older to work out the programming - it's more properly a hobbyist's tool, and a lot more adults than kids work with it. Any hobbyist with a bit of an interest in programming should definitely check out the Arduino.
