How are you going to scale up your storage to meet the demands of the users? Are you doing something clever, like Google Filesystem? This is not an easy problem, if you aren't prepared for it in advance. If 10,000 users sign up tomorrow... you might be very very hosed, as opposed to very very happy.

Amazon S3

Look at the prices for S3:

$0.15 per GB-Month of storage used. $0.20 per GB of data transferred.

So, that means Dropbox is going to have to resell S3 at a premium for the added value of these nice Coda-like features. Would you pay a premium for these Dropbox features? Maybe, I don't know.

Also, what's the typical use case? How much bandwidth/storage are people going to consume? Because, if I store 100 megabytes... my bill will pennies every month (going on S3 prices). You cannot transact pennies per user per month. If you could, then you've cracked the micropayments problem wide open. Maybe there would be a base fee? Like $5/month or something. Would people pay that much for online storage?

I don't know how other revenue generation models can be applied. Advertising? Selling a user's data to other businesses? (What's the privacy policy?)
