It's pretty easy to send just about anything to your Kindle, but if you're looking for an even more automated solution, Kindlebox does the job by linking a Dropbox folder to your Kindle and sending anything over automatically.


Once you authorize Kindlebox on both Dropbox and Amazon, you'll have a new folder in your Dropbox Apps folder. Put any PDF, MOBI, DOC, or other type of Kindle friendly file in there, and Kindlebox will send it over to your Kindle automatically. If you use both Dropbox and your Kindle a lot, this makes syncing the two up a lot easier. Unfortunately, you can't delete stuff directly from the Dropbox folder, but you can delete from your Kindle as normal.
