Yes, 100%, you won’t regret it! 
As a beginner I would recommend starting with Programming Elixir > LFPWE > Programming Ecto > Programming Phoenix 
Yup e-readers are great - I loved reading on my original Kindle. Now tho, my favourite reading device is the iPad Pro.
I loved my Kindle so much that I bought an Oasis, however it’s a downgrade if reading indoors imo - they have added a thick glass/plastic in between the ink and the surface (for the backlight I think) and my eye keeps focusing on the surface! The iPad display is much nicer. I’ll only use the Kindle outdoors or if I need to carry something light, but for indoors, I feel the iPad Pro is close to perfect (just make sure it is is aeroplane mode to cut down on EMF).
