For the two people in the world who were wondering this, GNU Emacs runs just fine under Debian on a Raspberry Pi. It doesn’t leave much memory available for other stuff so don’t expect to do a lot at the same time as you’re running emacs. But it works!
sudo apt-get install emacs
I was fortunate enough to manage to get an order in for a Raspberry Pi a few weeks back and finally received a unit.
The Raspberry Pi has gotten a lot of press… it’s a tiny, very inexpensive Linux computer. The basic specs are minimal (700MHz ARM processor, 256MB RAM, boots off SD card) – but when you consider that you’re paying roughly $35 for a board, it’s quite impressive.
