I always look at roaming when outside of the city charges in a monthly/yearly perspective.
I'm paying $40 with wind over $60-80 with someone else. I might roam a bit some months, but rarely $20-40 in roaming so each month although going over on my bill I am still saving money.
Even if one month I do spend a bit more than $80 with roaming in there over a whole year period I should still have saved money throughout most months making WIND the no brainer for me.
