Wacom one is my favorite and I have had them all (LAMY, Kindle scribe premium, Remarkable Marker and Wacom). I use the Wacom daily with the button hack to use it as an eraser. the button is far better than flipping for the back. Scribe has both eraser and button and all I use is the button.
My order: Wacom One best > Kindle Scribe > Remarkable > Lamy
Lamy for me was too light, cap just gets in the way and button placement is poor for my hand. sold it on ebay
i am fully in the apple ecosystem and love the remarkable. I take a lot of written notes and liked my iPad, but the Remarkable is another level. Considered going back to the iPad a couple weeks ago and hated the writing experience now that I have remarkable. your wife will love it
