The latest addition is a new keyboard and a new mouse from the Raspberry Pi Foundation which cost 15.60 British pounds (190 kroner) and 7.30 British pounds (90 kroner) respectively at the online store The Pi Hut. If you choose to buy both, you get away with 22 British pounds (270 kroner).

Both accessories are red and white, but grey-black copies are in the works. At the time of writing, there are only British, American, Spanish, French, German and Italian keyboard sets to choose from, but hopefully a Swedish keyboard will come eventually.
More information about the accessories can be found on the official Raspberry Pi blog.
