Well...it finally happened.  Everything was going so good too!!!  Just today, typing along and it just froze up on me.  I just unplugged it, grabbed the other mac's wireless and started using it.  Any thoughts?

Well that's certainly odd.  It's strange that keyboard then worked as long as it did.  I have continued to use the keyboard we exchanged with no problems whatsoever.  So it really seems to point in the direction of the USB bus having an issue.  Very very rare to see a problem like this.  Very hard to replicate as well.  

The apple store would suggest troubleshooting the software side of things first.  If the problem is consistent once it starts then it would be interesting to know whether it carried over to another user as well.  That would tell us a great deal.  If you have a test user on the computer then logging into it once the problem happened would help identify the problem more specifically as well.  Because, as with any software problem, it must first be isolated to either being system wide or user related only.  Although in this case it doesn't seem likely to be software to me. Feels more like a problem with the USB bus.  I say bus and not port because we know the issue happens with multiple ports.
