I currently have the full-sized wired keyboard. I like everything about it except that it's wired. I'm thinking about getting the wireless keyboard. I can deal with replacing the batteries and the missing NumPad and Delete/Home/End/PgUp/PgDn keys, but the one thing I really don't like about it is the fn key in the lower left corner (I'm so used to having the Control key there). I'm willing to give it a chance but I'm not sure if I can get used it at all. Who here has made the transition? How long did it take?
