Has anyone tried how .mac mail and calendar work on iPhone or iPod Touch? If mail works, that would be a big step forward for people interested in a Touch as a PDA replacement. For the calendar, I would think that being limited to hot spots would still mean no usable calendar, but if you could edit it off-line somehow, it might be a work-around. Finally, I suspect this is not in the cards, but what about synching the iPhone/Touch with .mac from the road? That would be a potentially cool feature, no?
