My light usage turned into over $80 for a week. I got the $10 US data roaming option last year for a trip to NY, cost me about $15 for a couple of days worth of emails and map usage, not too bad I thought. So this year I did the same thing for a week long trip. Mainly map and email usage turned into over $80. I'll take what not to do for $80 Alex.
RTWOM has a good suggestion, however that won't include data. This is why I'm thinking of getting a 3G iPad in the US for my wife. $15 should cover my 3G needs for a week at a time no problem.
Not suggesting you go out and get an iPad for this reason alone. If you are getting one anyway, this is something to think about. Otherwise look elsewhere for a solution.
