Ask HN: How much time you spend on digital devices ( PC + tablet + phone)?

I would consider my use to be pretty moderate, probably around 9-10 hours. I'll bet you also find a lot more people using these devices for work, reading and information here than you would find in a general public cross section as well though.

Since this is HN, I would guess most people will respond similarly to me: A LOT. If you are looking for a number, I would say about 12 hours a day.
