I agree--a tablet will hardly save you anytime (it takes forever to type on those things). Especially if you have epic--it's so quick and easy to type in those notes on a computer. Plus they add a fair amount of weight to your coat--I really liked keeping my coat as light as possible. They may seem light at first, but as the day goes on...
I was a TY as well last year and while my attendings were all very nice, they had the same expectations of us as the IM residents--I'm not sure I'd count on them not caring what you do. Rounds can be long and boring on occasion, but you learn a lot. Take advantage of intern year to learn as much as you can--you're only an intern once.
