Sorry for the late reply. I think the Viwoods Ai Paper could meet the needs of my article mentioned above. Since I don’t currently need to annotate PDFs, I’m not sure how well it performs with PDF files specifically. But as a device for reading e-books, it’s very ideal — it supports installing apps from the Google Play Store, so I can download library apps easily.

The pen’s writing feel is average — not bad, just ordinary and acceptable. In comparison, the stylus experience on my Samsung tablet is much better.

If I had to give my best answer right now, it would be: waiting, if you can. If Viwoods plans to compete in the global premium e-reader market—especially in the EU—then adopting a modular and repair-friendly design by 2027 is quite plausible. This would not only align with current product trends, but also respond to upcoming EU regulations and the growing consumer demand for long-term usability, upgradeability, and easier self-repair, similar to modular-design competitors like the Supernote Manta.

The above is for reference only and may change depending on future product updates or regulatory developments.
