This months ‘MagPi’ magazine in hardcopy version includes a free P0 stuck to the front cover. I’m reasonably sure it’s the first time a full linux computer has been given away with a magazine, but I could be wrong.

See also https://vimeo.com/146893658 for the official release video, and indeed the foundation website blog at https://www.raspberrypi.org/blog/raspberry-pi-zero/

At 1GHz even a single-core bcm2835 runs Squeak/Cog/Spur quite nicely and Scratch can run Asteroids at 45+ fps, and PacMan (which originally managed <1fps on the original PiB with original Scratch image) trots along at ~12fps. 

Using the ‘Shootout’ benchmarks Eliot favours for large non-UI testing, the P0 will score around half of the Pi2  - but with the Cog/Spur vm it is about 5X the orginal PiB system when this all started in2012. 40+ Dorado for $5 seems a pretty good deal.

Of course, the web is alight with complaints that it isn’t a quadcore multi-GHz Xeon with terabytes of ram and petabytes of ssd. Oh, and it costs too much, apparently.
