One way to avoid kindle fees is to use USB to sync. If you're on Mac, use Ephemera (http://goephemera.com/), or if you're on Windows, use Wordcycler (http://www.wordcycler.com/). (I'm the developer of Wordcycler.)

Another great benefit of these programs is that you can sync individual articles, not just the pre-made bundles that Instapaper provides. You can plug in your device, have the program download the articles, and automatically eject it. Later, when you finish reading an article on your device, delete it, and it will be archived on Instapaper the next time you sync.

And for Linux, check out calibre: http://calibre-ebook.com/

I second Calibre. I supposedly works for Mac too. I use it for Windows and on my Sony PRS-600. Calibre offers lots of ready-to-use web subscriptions which gathers articles from other websites like an RSS Reader.

I'm aware but consider the $.15 well worth it. I maybe sync with instapaper 6 times a month.

It is really nice to treat the kindle as a stand-alone device. The last thing I want to do is stress about hooking up to my computer just to save some change.

That sounds REALLY lazy, but I have to say, deciding to be lazy in this instance feels great. As long as I remember to click 'Read Later' once and a while I know I'll always have something great to read wherever I am.

I tried to get Ephemera, but it crashes on launch any time I try to open it. Unfortunate because it looked pretty useful to me. I realize you (probably) aren't the author, but thought maybe others on here were having problems with it. Gonna send in a crash report, no idea what's causing it.

Thanks so much for mentioning Instapaper--I had an account but forgot about it. Just finished queuing up some reads I've been meaning to get to!

This is also true on the iPad and it's way cheaper. I could never quite stomach the Kindle delivery fees.
