Wouldn't it be appreciated if we could tell the free power-ups from the non-free?
I like to explore as much as the next person but 5, 14, etc. day trials are a waste of my time. Plus, we need to go through all the steps learning, etc. and it just further turns us off to the whole idea of paying for something - we are used to the mobile model of a lite version and later in life going with the pay version if we find value.
I'm very frustrated with dealing with marketing hooks that don't really work. (I understand the need to pay for good things, our kids need to eat, etc. but that model has been improved by the apps-lite market long ago.)
