i try not to take mine to bed unless i'm really into what i'm researching. mostly i use my tablet for keeping track of seeds/plants and listening to music while in the yard planting. i've used it a few times to take pics of things but not much since the camera isn't very powerful so they come out grainy looking.
it is much easier to tote the tablet than it is the 6lb laptop.
I sometimes take my tablet to bed. I usually use a pencil, but crayons make the work I'm doing more fun and colorful. Most of the time I use lined paper.
I sometimes take a tablet to bed and lay it on the bedside table. That way, if I wake during the night with a headache, I can reach over and take the tablet with a sip of water rather than getting up to find the aspirin in the dark.
Dinosaur time again. If someone sent me out seeking a tablet, I'd be bringing one down from the mount, not stopping at Best Buy.
