It was no surprise my favorite app, Evernote is very useful on the iPad. What I didn't expect is that my second favorite app, Dropbox would be useful too on the iPad.
I use Dropbox to share files with my family, and with a collaboration team I work with every week. Almost everyone who my wife or I have drawn into using Dropbox for a collaborative project, end up using it a lot personally and pushing it out to their friends. That is the very epitome of Freemium.
I wasn't quite sure how that would work on an Apple product. The iPhone, and iPad do not use filenames generally in Jobs' efforts to keep things simple.
The free Dropbox app for the iPad just works. Once installed, you give it your Dropbox credentials (username and password) and then you see all your files.
If you touch an MP4 file, the video plays. If you touch a PDF file you see the file.
The quality isn't the same as you see in the dedicated Video app or web browser for the PDF, but it is useful.
Dropbox makes it very easy to send files to your iPad, or to a friend's iPad if you and they have a shared Dropbox file folder. And any file in your Dropbox is available to all your computers.
Shameless Plug : if you sign up for your free Dropbox account through this link, Dropbox adds 256 megabytes to my account. It has no downsides for you. Thank you.
