I've been trawling the forums trying to get a better understanding of what I've got myself into and see that Bredman says
The Fedora Remix is definitely not recommended for new users. The default distribution is Debian. Please use the downloads from http://www.raspberrypi.org/downloads
unless you really know what you are doing.
I'm not a computer newbie - started with a Sinclair ZX81 and graduated to BBC micro and enjoyed playing with Basic programming before migrating to Windows on PCs - but when I got my Raspberry Pi and went to the download page, I heeded the warning that if I wasn't sure I understood the information there, I should go to the forums on the RaspberryPi site for information. From the Rasberrypi.org page I browsed to the wiki and then to http://elinux.org/RPi_Easy_SD_Card_Setup
From reading this page I understood that I should be using the Fedora installer. It seems I was wrong.
However, I'm not sure Debian will be a lot easier. After reading on the forum about the difficulties people are having with SD cards (even it seems ones which are listed as "will work") and with Debian, I think I'd bettter put the Pi in a drawer until some of the teething problems are sorted out!.
