there used to be a full sized wireless keyboard? I am a programmer and find the small wireless keyboard hard to use (the small arrow keys and lack of home/end keys). From what I remember there used to be a full sized wireless keyboard, is this correct?
Yes, you can even still purchase it from vendors listed on this Google Shopping page. Unfortunately, that option will run you $120 plus whatever shipping they charge.

An alternative is purchasing it used off eBay, but I only found one listing for the full sized wireless Apple keyboard.
