Long story short, music.apple.com will look very good in a web browser on Android, but (with German location anyway) it will only ever play song previews, never full songs, no matter how hard I log out and back in again. The only download advertised on the website is the Play Store, though.
Here’s my personal comparison of Android ebook readers for my Boox eink tablet. I would love to add drawings as annotations. Ratta Supernote devices do this splendidly by storing the pencil input directly, without handwriting recognition. (Example here.) This is the gold standard. Everything else requires multiple apps (to draw a diagram, for example) and import/export (of notes or EPUB book locations), which is also acceptable, but not ideal.
