I agree. (though, I have been arguing with my colleagues on this site for a couple of days now about this very topic, be careful, angels fear to tread here)
Element14 (Newark Electronics) recommends at least a 1.8A switching supply, and provides a recommended 2200 mA switching supply for sale to their Raspberry PI customers. Personally, I would not power the RPi with anything less than a 2200 mA switching supply with a relatively short cord and a good connector. Brown-outs and resets are common with RPi users because they 'cheap out' on their supply and try to go with inadequate power. There are even some folks on this site who claim to run their PI off their monitor's hdmi connector (and other ridiculous schemes). Well, its their PI, they can do with it as they please, yes?
