There are many Micro-USB chargers which would work as the power adapter to power a Raspberry Pi with AC power from a wall’s power outler. Your current smartphone, and tablet micro USB charger may work with the Raspberry Pi, but if you want to overclock the Raspberry Pi, or use the Pi for more power intensive tasks like video playback, and gaming, using a Raspberry Pi with 5V/Volts of voltage, and 1A/Amp or higher of current like this Raspberry Pi 5V 1A Micro USB Power Supply would be best for powering your Raspberry Pi.  I also recommend picking a power supply with a longer power cable to make plugging in your Pi more convenient when the power outlet, or surge protected power bar is farther away from your Raspberry Pi.

To turn off the Pi, you need to shut it down in Raspbian desktop application launcher on the bottom right of the desktop

You can also type sudo halt in the command line or LXTerminal if you are not in Rasbian. Lastly, you need to remove the power adapter from the Wall’s power outlet to turn off power to the power supply, and the red LED light on the Pi’s circuit board.

It is very simple to install Raspbian, and other compatible operating systems to your Raspberry’s Pi’s SD card in under an hour.  Installing an operating system on the Pi is simpler than installing a desktop operating system on a Windows desktop and laptop in my experience. You just need to format your SD Card, and unzip Noobs zip folder to your formatted SD card. You can also use Win 32 disk imager to write operating system images to your SD card, and backup your SD card to a .IMG file, so you can make multiple SD cards to share with friends, or for use on other Raspberry Pi computers which you own.

If you need a SD card, I recommend Transcend 8 GB Class 10 SD Card because it is fast, reliable, cost $7-8 US Dollars, and is compatible with the Raspberry Pi in my experience. 8GB is also enough space to install a few operating systems if you use NOOBS or Berry Boot to create a multi-boot SD card for running more than one OS on the same SD card.

I recently been using the $35 Raspberry Pi Model B 512MB version as a mini desktop computer which you can use for many tasks like playing classic games like Quake 3, watching video with XBMC, making a web server, using as a wireless router, and other tasks while also saving money since the Pi only cost $35, and it uses very little electricity. I seen videos online of people using the Pi to make a mini laptop, classic game console for playing older games, using it as a media player, making a digital camera, robotics, and many other fun, and interesting activities.

I like how quiet the Raspberry pi is since it uses a SD card instead of a hard drive, and it has no cooling fans, so there is no noise from the Raspberry Pi like a traditional laptop or desktop which makes noise because of mechanical hard drives, disc drives, and cooling fans. The Raspberry Pi also uses very little power since it uses a Micro-USB Cell phone charger to power it, and the CPU, RAM, and other parts on the Pi does not use a lot of electricity.

The Raspberry Pi also does not generate much heat, so it would not heat up your room like more power hungry, and hotter running computers. You also do not have to manually clean dust out of the case fans on a Raspberry Pi like a traditional PC and laptop because the Pi has no fans, and don’t require additional cooling.

The Raspberry Pi is a good computer for using XBMC to stream/play video and music from a USB drive, the internet, or another computer you own. It is also good computer for learning about computer programming since Rasbian, which is the Raspberry Pi operating system, comes bundle with computer programming programs.

The Pi also can be used as a web browsing computer for browsing smaller text and image based website like forums, blogs, and static websites, but it would be a slow experience when browsing bigger websites with lots of animation, images, and background music compared to browsing the bigger site on a regular desktop computer. I recommend using the Midori, or Netsurf web browser which comes bundled with the Raspbian operating system for the Pi. There is also Ice Weasel Firefox and Chromium ,and Opensource version of Google Chrome, web browser which you can install manually on the Pi.  I used the Pi to visit blogs, forums, e-mail websites, news sites, and search engines. The Pi loads most sites at a reasonable speed. The speed of page loading takes a few seconds more than a desktop PC which is more powerful. If your internet connection is not very fast, you may not notice much slow down when loading sites. But, I recommend only having 1-3 tabs open on your web browser on the Pi because having too many tabs open may slow down your Pi.
