I have the MS Surface Go 2 & have it running Calibre; still lighter than a printed book. No problems with Calibre & being used as an ereader; have install freda+ as the ereader app. OS is windows 11 pro but cpu is not eligible to run the android subsystem.
Loaded Calibre onto the Go 2 via the windows free robocopy which was set to use 3 threads to copy the desktop Calibre Library onto the tablet (I have only 980+) books. Surface Go 2 has a 10.5 in display.
Check
www.tabletmonkeys.com for other windows tablets in the 10+ display range. Am being tempted to see which ones can run the android subsystem. And my desktop has the WSA installed & now using moon+reader pro as the reader app on the desktop; WSA is now using android 13.
