One of my reservations about the value of the Arment opinion piece is that he owned the rMB for a day. That's better than most people who fulminate about its alleged shortcomings, who either haven't even seen the thing or at best have only poked at it for two or three minutes in the store. In most cases, you need at least a couple of days to give a new machine a reasonable audition, and a couple of weeks (the return period) is better.
Completely agree. One day is not enough. Have to say your feedback on it has been very helpful and balanced, though at the end I have decided to get one and use it during the 14 day period before I judge it. It's just a matter of them having stock in the local Apple Store.
