Far worse than that -- Microsoft's keyboard designers decided to go in for a collective lobotomy some time ago, and redesigned their entire line of keyboards (office, gaming, multimedia, wireless, internet) to use (vertical) island of *5* keys instead of 6.
I've got the opposite problem. Got a MS natural multimedia thingy at work with the 5 key vertical island (was the only natural USB keyboard we could get at the time) and hated it at first. But now I've got so used to it (and I'm a Ctrl+V guy anyway) that I now can't use my keyboard at home (an old MS natural one with a "proper" 6 key horizontal island). I'm looking to replace it with a 5 key vertical island one so they're both the same, but they all seem to be bloody wireless - which I hate - we spend enough on batteries for the kids toys as it is :-)
