Raspberry Pi is a 35 dollar computer, but it’s a computer with a whole lot of power. When you connect a monitor, mouse, and keyboard, you can use it as a computer with an operating system called Raspabian. This system gives you the ability to code in things like Python and Scratch, and it also gives you Minecraft! The real power of the device though is in all the customization you can do! You can add things like breadboards, hats, and cameras to make the Pi anything you want it to be. You can even change out the operating system for even more customization!
The Model B + take all the processing power up a notch. It takes the actual processing power up from 1.2Ghz to 1.4, and it makes a drastic improvement to both its Ethernet networking and wireless networking features. It also adds a cool feature which allows power to come through the Ethernet port. In the end, they might not be drastic changes for many users, but anything to make Raspberry Pi better is AWESOME.
