I do this - all my technology is in another room of the house. My computer, phone, TV, none of it is in my bedroom. I just plug my phone into a charger in another room overnight.

The only concession to technology in my bedroom is a DAB clock radio. I'm not interested in checking Twitter or email or whatever from bed, but if it's there, I'll do it instead of sleeping. So just keeping all that stuff in a different room works!

This article is nonsense. It's just a sales pitch for some software. Going on the computer and writing your notes in that software just before bed is likely to harm your sleep, as is going on a computer to do anything right before bed...

True, I have the urge to check my mails often when my system lies in front of me, I made it a point to keep my laptop inside its case before sleeping and this has reduced the email urge to a great extent.

But but... My phone is my alarm clock too. And my music player. And bedside flashlight. And the PC is the HTPC for my TV...which I watch when falling asleep.
