[Quoth]

Most people get a Sage simply to read. That's why the Pen isn't included.
Many get an Elipsa for comics or PDFs.
I'd only use the Pen on Elipsa to "doodle" notes on PDFs. I quickly realised after buying it that though I'd not been interested in 8" Sage as I had a 7" Libra, that the Sage could be far better for notebooks. I wasn't impressed with the reMarkable as it's only networked USB (no Calibre) PDF viewer and basically the Notebooks are a fancy sketchpad. No library system, just a file manager.
So I no longer use Jota on Android or paper notebooks. But the Wife has a Sage too because the 8" vs 7" is more like reading a paperback (she had a Libra) but never ever uses the notebooks.

If I want more than notes I use PC or laptop. The Android tablets now only used for Solitare and Viber (oddly like Kobo also owned by Rakuten).

My desktop PC has a UPS, so as safe as laptop for content creation if a power cut or someone trips the box. So I only use laptop now if doing stuff when visiting someone.
