Thanks very much! I keep hearing about this Raspberry Pi thing and I have no idea what it is! It certainly sounds interesting and clever. Thanks for the post about Vinux - I did have a look at their website, but can't quite work out how it helps or what it is like - have just burned it to a dvd so might try it out tomorrow, but the Raspberry Pi thing sounds good if it is just something that works on the TV - assume you need a separate keyboard and mouse?

The Raspberry Pi is a single board computer, using an ARM processor. It is a low power hobbyist/experiment computer, but also serviceable as a system for those who want something very small. This is the main website,
http://www.raspberrypi.org/ but a problem I feel it has is that it's somewhat similar to a blog in that some new posting by someone changes the content on this main page. I recommend you visit the
FAQ Page because this shows diagrams and pictures of the Raspberry Pi, where you can buy them, and diagrams of the connections that the board has.
My recommendation is that someone starting who is interested, but realizes that it may take them a few days of experimentation to get it all set up is that they purchase a Pi board, along with a 4 GB or 8 GB SD card. Have available a USB mouse and keyboard, a monitor, plus HDMI cable. Other things to have are an existing Windows computer capable of using/viewing the SD card. The monitor may be an issue; for instance we have one monitor here which has HDMI, the rest have DVI so we had to buy an HDMI to DVI cable to go from the Pi to our monitor. Otherwise if you have a TV or monitor with an HDMI interface, then you can just buy an HDMI cable; similar to one which goes from say your cable box or DVD player, to your TV.
Typical situation is that the tools to format and set up the SD card are there and ready for Windows. There is a Linux process, it's just less automated and the core instructions start by describing how to set up the card from Windows. Once you boot the Pi from that SD card, you have the option to install one or multiple distributions. I've installed the Pi default version, it works fine.
From there you can explore the Pi Linux and set up the system to work how you wish. Many use the Pi for projects, therefore they're looking to do certain things with it. But if you just wish to set up a home system for someone to use, then some ideas and things to consider.
The board is small, they sell enclosures for it. Basically you'll have a small box about the size of an index card, but a little over an inch high with a bunch of cutouts for cables. The SD card pretty much stays in there all the time. There are two USB ports; however this is NOT a high powered board and attaching a non-powered USB HUB and a bunch of peripherals is going to cause stuff to not work, or not work completely. So a powered USB HUB is good, there was one which I cannot locate now, it's cool because (a) it's small, (b) it is powered, and (c) it has a special port labeled for the Pi which is intended to output 5V to go into the Pi microUSB jack and power the Pi. That reduces the number of wall plugs one needs. To have that third (or more) USB port is good. Two are used up by keyboard and mouse, and then one can plug in USB flash drives or thumbsticks to contain their data. Not that you can't store data on the SD card, my point there is that rather than use space on that card, have your data be removable media which also doesn't contain your operating system.
I can't testify whether the Pi works great for movies or games; I've used it to do Linux, web browsing and such, I've also not hooked up speakers; however one use of the Pi is that people use it as a media device, be that server or gateway; in their houses. I'm not sure how far they go with it, but I'm sure that someone has tried. It's just not an area I've looked too much into, we use them at work for cheap projects which require more than an embedded CPU, but need to be less than a full blown x86 architecture. As far as how usable a Pi is for everyday use, it seems serviceable to me. But this is why if your interested, but not fully sold; I recommend you start with just the board, SD card, and ways to hook up with it, keyboard/mouse/network cable. Then if you decide you like it, you can look at boxes and see about adding drives and speakers, etc.
