Worthy of mention, gp32x’s wejp has ported Arch Linux to the Pandora.
Arch Linux is a distro with the ethos of keeping it simple, pure and modern. Find out what Arch Linux is all about here.
The two main issues with getting Arch Linux running on the Pandora are, 1) Arch is compiled for i686/x86_64 and 2) it’s a bit fiddly for the average user.
To the rescue is PlugApps. Sounding more like something you might add to your browser, it is in fact a port of Arch Linux to ARM and a full distro in its own right. Intended for the likes of the SheevaPlug and associated hardware until, that is, wejp has done the necessary to produce an alternative OS, complete with GUI and some Pandora specific tinkering.
One advantage of running an OS from the SD card is that you can use the integrated package-manager. Arch Linux has a particularly nice one called pacman. Also this OS is based on a more recent version of the Linux kernel and will have more up-to-date packages, which brings its own merits, but the flip-side of this is that you are likely to run into dependency issues with some PNDs. Go to the forum page for more details on this.
wejp is currently working on bringing the automated PND support (what you are used to from Ångström) to Arch as well as his own music player GMU while other users have been busy porting various programs, a list of which you can find in this (German) thread.
Whilst porting PlugApps Linux on the Pandora is a guru activity, installing it on to a SD card is not. To get started read wejp’s blog for the download link and instructions. For now, you will also need to update the kernel to avoid a keyboard bug. Follow these simple instructions. An updated image is planned for release in the near future, which will make installation that much easier.

On that note I recall that I never gave kloplop321 an introduction, for which I apologize. Also a big welcome to him, who we will be seeing more Pandora related videos from. --foxblock]
