Hello Hive-

So, I thinking about trying Podfitness, but I wanted to ask a few question of anyone who has tried it, just to make sure.  First of all, once I download a workout, does it stay on my ipod for good, so I can go back to it?  And do you need to keep updating your ipod all the time with new workouts?  Also, what's to keep someone from just downloading a ton of workouts during the free trial period and then canceling early?  And what are your reviews?  I'd love to hear from you!
