For those that want more, buy a raspberry pi, the new one has 8 Gb memory and a 4 core processor.
Run a 64 bit Linux on it and you have a repo wih thousands of apps. If you let it boot from an external
USB 3.2 (10 Gbit) 240 Gb SSD it will be fast.
I received mine yesterday just have to assemble it.
With a bluetooth keyboard and mouse you can serv the tv and the raspi.
