Yep. Get dropbox! It's free.
I also use FTP Pro to upload images from my ipad to my web server, where I can easily retrieve them for the "Import from URL" part of Hubpages capsules, but FTP Pro isn't free.
Tip: Click the belly button AND the power button at the same time to take a screencap. Very useful if you're writing a hub about using the iPad for something!
