One weakness I saw with MagCloud's pricing model is they do not seem to allow the publisher to set a price that is lower than the sum of the per-page costs. So you can't directly subsidize the price for the consumer, say with your advertising revenue. They currently require you to pass the full page-based cost on to the person who buys a printed issue. So large page counts make the issue price pretty high, possibly pricing you out of many markets because of it.
This inflexibility may be the cost of getting the overall convenience of the service, but it's the biggest disadvantage I've seen so far when considering it for my own business ideas.
