You copy the URL to the paywalled article, paste it in archive. In most cases, someone else has already archived it already and it's ready to view.
I also use Bypass Paywalls for Firefox in the browser, this takes care of less intrusive paywalls - for the big boys (big news orgs) the archive.is solution is the best.
Very appealing for a travel device running a Linux kernel. On the product page, they also mention Open Warranty, which makes me believe it will be easily serviceable - this would be a big plus, especially for a travel tablet, being able to switch the disk easily.
