Been using a iPod Touch when on the road for about a year ane it works pretty well for most pages. Some pages though get cut off at the bottom though. I know boxscores only show the visitor and about 1/4th of the home stats. I think player pages are incomplete, too.
Not sure, but I think some other types of pages don't show up completely, maybe the pop-up type pages. Had the same issue in FC Dynasty as well. But it doesn't cause any problems for anything important. When I've had to recruit on the Touch, I've had my list of players ready to go on my recruiting page. It's a bit cumbersome, but do-able.
Never a problem in game planning.
