File Sharing with an iPad: Ugh

there are some clunky 3rd party apps to print, but most require a utility installed on your mac or pc to proxy the print requests, and since no other app can access your email database, they all have to reimplement an email app inside of them, in which you have to duplicate all of your email settings. ugh indeed.
The way it ought to work is the devices should be sharable via Bonjour, just like any laptop or other smartphone, and you should be able to drag things between them.
Note that due to multiple uses of the 'should' word the above is about as likely to happen as me getting hit in the head by a lemon peel wrapped around a gold brick.
