Would you rather do things on a small screen or a large screen?
Double edge sword question! Video relay via iPhone/iPad is a lifesaver when we aren't home. Larger screens are nice to use at home because it's easier to see. Video relay is nice using lg screen TV. I use video relay via iPad a lot.
I hate to be a pain, but... medium. And it depends on what the "things" are. And whether I'll need to be wandering around while I'm doing it.
What sort of ... "Things"? :-*
I used to think my answer to this would be small just because I use my phone more often than my computer, but I've come to realize that I prefer to be using my computer for most tasks.
Large, if it's practical to do so.
