Debating on picking up the X4 Pro even though I have the regular X4

Hello everyone ! This device has really helped me start reading in my busy everyday life & I LOVE it. That being said, I have found that I usually like to read at night so the regular x4 has been really hindering me as of late due.

Is picking up the pro worth it for this? I am on crossink in my regular x4. Is it available for the pro? What really are the major differences if there even is any? Thanks !
