Switch to BOOX for e-everything? (reading & writing)

I love e-readers, I currently have an old Kobo that I plan on updating sooner rather than later. Someone suggested I switch to a Go Color 7 for what I want:

• e-books. either my Kobo library via app, but preferably from Bookshop.org's new app*
• read the news, either via app or web browser
• articles saved to Pocket
• library books via Libby
• write long-form documents (ie, more than just a Notes App) ?
• connects to a physical keyboard (bluetooth or proprietary) ?

Perks but not deal breakers: stylus writing, color screen, page turn buttons, audiobook playback. I read manga sometimes, but use an ipad for that.

I basically want an ipad mini with e-ink; an all-in-one device instead of switching Everything over from one locked ecosystem to another (because then I'd just stick with Kobo). So would a Boox tablet give me everything I hoped and dreamed?

*also open to converting my kepub books to regular epub and switching entirely to Bookshop
