Port of Espruino to Pi Zero - native - no Linux

Thanks! I don't think it's really highjacking the thread much :) Support for all types of Pi would be a major bonus for the Linux-based release.

though I must admit I do not find my rpi model Bs fast enough to use for Arduino development

I think with Espruino it'd be pretty speedy. After all, all the work gets done in the web browser, which would be running on a proper PC :)

I think the rpi has demonstrated that it is not necessary to "hide" linux to make the system attractive.

True, but if I'm honest I think the real thing that has 'launched' the Pi is the massive community around it. You can just google what you want to do and then copy/paste the commands :)

... also quite a lot of people use the GUI! :)

Carambola existed some time before the Pi (I think?), was cheaper and had Flash, WiFi and Ethernet on board, but I think it failed to become popular mainly because of the way people were thrown headfirst into Linux.

Somehow the Pi just got it right...
