Right now the app only supports the free method for sending articles to a Kindle, which means no 3G if I’ve understood things correctly (as I said, I don’t have a Kindle). Paid transfers will come in the next version, and by “paid” I mean “to Amazon” – the developer won’t charge you beyond the cost of the app, which is $2.50.
Services like Read It Later are quite popular, and this is basically the ultimate version of that, transferring the text to an e-ink device in the process. While I personally prefer to read on LCD (I’ve had an e-ink device before, so I know for sure) I can imagine this is the holy grail for people who read a lot online but prefer an e-ink device for longer pieces.
