When it initially shipped earlier this year, the Onyx Boox Max was only available through a single retailer in Europe, and now the 13.3" document display device more widely available.
The Max runs Android 4.0 on a 1GHz CPU with 1GB RAM, and 16GB internal storage. Its 13.3" E-ink screen has a resolution of 1600 x 1200 and works with a stylus (but not your fingertip).
As I pointed out in my review, the Max is less of an ereader than it is a device for displaying documents like PDFs. At 570 grams, it's rather hefty compared to its competitor the Sony DPT-S1, but not enough that you would notice or care.
In related news, Sony has marked down the DPT-S1 to $599. This device has a similar screen with two types of touchscreens, but it only supports PDFs.
