I already have the PI2 Model B and now wanted even a comparison on a budget have the predecessor, with which I can kinda rumexperementieren with the GPIOs. 1) Anyone who knows a little with PC's and electronic and employs, a Pi should call his own. 2.) Do not fear the unknown operating systems, Rasbrian is from the surface a little like ne abgespecke XP version, and everyone should quickly get used to the surface. 3.) WLAN etc. is (unlike XP) detected and installed immediately. 4.) If you like programmed to be Pyton (preinstalled) to heart. With a little training (had until 3 weeks ago never programmed what) succeed or initial success using a breadboard (costs about 5) can be quite simple on or off about GPIO. 5.) If we now consider the this little device will cost ~ 30, I'm not surprised at the success of the Raspberry.
Well - do not hesitate, but just once ausbrobieren itself
