We're all adults. We understand the social contract that surrounds our getting together for a game.
We've also been using laptops since the 2E Core Rules CD-ROM so we have some history with electronic devices....
I been using a computer to manage my char sheet since Appleworks on IIe. I even used CrossWorks to port chars from Appleworks to Word Perfect for DOS.
I quit printing out char sheets since around 2000. So a GM who banned tech would be banning me. I don't print anything if I can help it.
In the modern era, I find my iPad running a spreadsheet for my character is far superior to using a laptop. The laptop had to be always on, in front of me. The ipad, I could easily set it down and enjoy the game.
I also use real dice when I play. So the iPad's job is char sheet/inventory management and looking up skills/feats/spells/rules.
