Boox Note Max. a4 size, expensive as hell ($650 I think), but it runs Android, can install stuff from the play store or side load apk. Ships with a very capable document reader can handle ebook formats, pdf and has good support for drawing and annotations.

There's also the Box Tab X C, the color variant. Has color (and thus a backlight and the DPI tradeoff), and the pen is not Wacom.

There's also the Fujitsu Quaderno gen 3 as well - half the weight but can't do epub or mobi.

		Regretably, the Boox Note Max or Remarkable might be a better choice than any Fujitsu reader. I am on my second device from Fujitsu and I will not purchase another one. Like the Sony DPT readers, the Quaderno is would be great product ... however, 1. there is no customer service in the EU/US markets. Something broke? Bin it. 2. the devices are quite fragile, with poor longevity. 3. the closed source software does not support modern systems such as Apple's M4 Macbook series. Disclaimer:
