For sheer speed and ease of use, the combination of Amazon, Kindle & WiFi is very, very good.
I also liberate paid content, but find it quite simple to move/copy ebooks from my Kindle to Calibre for this purpose, so when new content is coming from Amazon, I use Wi-Fi or 3G to download directly to the device. Part of this is convenience: my Kindles live upstairs by my bed while my PC sits downstairs. I batch liberate, tag and otherwise organize my content via USB from my Kindles to Calibre about once a month. The rest of the time, I only turn on the Kindle radios when I know something new is coming from Amazon, or some news via Calibre and email.
