I have bought a connection thing from eBay which has a slot for SD cards and a USB port. The advert says it will connect to a keyboard with USB connectivity, I have found a few that have USB connectivity online but I don't want to buy one unless I know they will definitely work. Will I need to buy any special keyboard or will any one with a USB connector work? The ebay ad didn't say I needed any special keyboard but I just want to be sure from someone with more experience. I was thinking about getting the apple keyboard but I might just buy a cheap one for £10 from Argos! And I'm not interested in a wireless keyboard so please don't suggest this. They are way too expensive. Thanks in advance.
