The Quaderno A4 features a 13.3 inch E-Ink Carta screen with a resolution of 2200 x 1650 and 227 PPI. The screen is completely flush with the bezel and not only does this make the device have a premium feel, it also provides a ton of benefits. You can easily draw edge to edge, which is quite useful for people who are editing a full screen PDF file.
Underneath the hood is a Marvell IAP140 64-bit Quad-core IoT Applications Processor and ARM Cortex-A53 CPU, up to 1.2GHz, and has a separate power low-power Cortex M3. It has 1GB of RAM and 16GB of internal memory, but when you power it on the first time, there is 11 GB. The rest is reserved for the Google Android operating system and some of the stock PDF templates that are available.
This is basically one of the only 13.3 inch digital note taking devices on the market, other than the Sony Digital Paper and the Onyx Boox Max Pro. It has an English UI, so you can use this as your daily driver.
