For most users, it makes sense to buy the Raspberry Pi 3 Model B, which retails at $35 on Amazon. That’s the only model which comes with Wi-Fi and Bluetooth built-in, and includes a dedicated Ethernet port. When you buy a Raspberry Pi starter kit you are getting the device itself and a number of useful accessories to fit the needs of most general purpose uses. With a Raspberry Pi, you can do most things you do with a regular computer like web browsing, document editing, playing games, coding and much more. There are MANY Raspberry Pi accessories out there, but you just need a few to quickly get started.
