The website mentions a 4+ GB file if you want to download updates. (Download to your own MicroSD card and then swap them, there's no d/l capability in the WikiReader itself.)

It looks like they used a 4GB microSD card, but only included a subset of the articles (about 3 million). Given that my stripped-down version had over twice that many (6,044,424 inodes, most of them articles), and that the full HTML almost certainly takes up more space than their custom-preprocessed pages, the difference in size is understandable. On the other hand, unless their selection criteria is way off, the other couple million articles probably won't be missed; at least half of them are probably stubs, advertisements, or niche fan-pages.
