Well, that was fun.
The Gorse Fox now has his Raspberry Pi running and is remotely logged in to it from the MAC. It has several dinky little browsers and GF is using one of them (Midori) to write this blog post. He still needs to fiddle with the keyboard settings to adapt to the MAC and also the screen size - to make better use of the display size... but first impressions are good.
With a single power connection (micro-USB), and using a small USB WiFi dongle GF has it down to the bare minimum.
