Virgin Mobile opinions

Anyone here use Virgin Mobile. I use Straight Talk right now, the service is fine but their phones leave a bit to be desired.
I have been thinking of going with Virgin Mobile's Beyond Talk plan as I do more texting than talking and they have a better selection of phones. I would like to get the Blackberry because of some of the features it has vs. the phone I have now.

Just looking for any opinions on their service, both good and bad. Thanks
