It depends on the person. Right now though, since Mobilicity has 20c/minute roaming, for the few instances that I go on a trip I don't mind paying it. At this point Mobilicity as an urban carrier has a better value than a land line, so even if they don't have coverage outside of the city it's still a good deal.
The word 'Pentaband' means '5 Bands', from the Greek word 'pente' meaning '5'. For a phone to be pentaband it has to support 5 bands. If the phone has AWS support, it doesn't automatically mean that it is pentaband. The reason Wind and Mobilicity users like pentaband phones is because the reverse is true. We're not the only ones who like pentaband phones though, so please stop referring to phones that work on Wind and Mobilicity as pentaband. It causes unnecessary cofusion.
