The newer 2025 model is better in everything in comparison to the 2024 model so far.
Bigger screen size. The 11" fits an eu din a4 page better than the 10.2".
The newer frontlight technique looks a page more paper-like with less glossy parts.
The performance has been much improved for paging or zooming which feels lees e-ink and more LCD.
Handwriting is more paper-like because you feel scratching on the screen with the pen which is a better haptic feedback during writing. In comparison to the remarkable2 which I owned previously the 2025 model is close to that.
Honestly the 2024 model would be great and enough as a ebooks reader with annotation support but not as a working pad for writing math by hand.
Another thing I've mentioned is that only the 2025 model has the capability to export notes to Google or Microsoft cloudspace even both kindles run with the same firmware.
I know that there lot of yt videos for comparison but I want to share my first impressions.
