It's a mammoth packed in ant body, one can do much more but to start with it is bit hard.
Pros:cheaper
Cons:not so userfriendly as compare to arduino
It takes a while to get used to but is a great way to learn Linux. Originally designed for school childeren but great fun for grownups too. If you want to learn a little bit more about computing, get yourself a Pi 3 and get started! recommended!
Pros:great price! You can even use it as a web server!
Cons:SD cards wear out fast, use a USB stick or drive instead.
