The Kobo Sage is an e-reader and digital notepad in one. Taking notes requires a Kobo Stylus.
Keep in mind that it is not included in the price and costs 39.99 euros separately. Once you own it, you can scribble it in e-books or PDF files, or jot down your thoughts and minutes on self-complete pages.
Handier
The manufacturer already sold a similar device under the name Kobo Elipsa, but the Sage is a bit more handy because of the smaller screen of 8 inches (20 cm). This e-reader costs 289.99 euros.
