Totally blown away with ths little gadget, I've got 3 in the last week. I have one as a Kodi media center in my neighbours so they can watch the 7Tb of TV shows and Films I have attached to my Router, they have a Sony TV so it's recognised instantly and their TV remote works great with Kodi. I have 2 for myself, 1 as a media center in my bedroom and 1 to mess around with.
Make sure you get the good quality PSU recommended by Pi. I've been using various Samsung Galaxy chargers that I have laying around and it's quite evident that some of them are inconsistent with their output. There is a rainbow coloured square that appears in the top right corner when power is weak, even when there is only a TV connected via the HDMI , so I've ordered 3 Raspberry Pi 3 Power adapter UK/EU 5V 2.5A
Check out the online videos and Pi sites to get this set up correctly, with a weak PSU you can struggle to get the wifi to be stable or it wont even recognise a keyboard.
