“A full functioning computer for less than a pint of beer in a London pub? Despite coming out in 2015 and first appearing as a cover mount on the MagPi magazine, I am still amazed.
My Pi Zero is currently a personal email, contact and calendar server. Power requirements are frugal enough to power it off the USB port on the ADSL router. The 512Mb RAM and 1-core CPU just about copes. This one is the redundant spare. ;-)
Somehow 8Gb 4-core Pi4 costing 15x as much as the Pi Zero is kinda drifting away from the original idea and providing geeks with an ARM Linux desktop with dual 4k outputs that (for me) doesn't quite cut the mustard. I can imagine compile times on an SD card are a world of pain ...
But still, supporting your products well beyond the initial sales cycle must be applauded. Thank you Raspberry Pi Foundation ... Eben, Liz et al.
For me, the Pi is a general purpose appliance that can be deployed around the connected home for way less than the equivalent commercial product: Volumio+DAC is my audio server, people use Kodi for films and stuff, RetroPie to play those old games. and an Apple Time Machine for backing up your overpriced laptop etc.”
