Hi Darrel,
There is a difference between the paid-for and the not-paid-for versions, that does stand out. The not-paid-for version always pops up a window with a link for licensing information each, and every time you run it following an assembly of your code.
It may seem like a minor annoyance, but it can start to get to you after a while.
I also kinda like the idea of paying for the upgrade (although the pricing and delivery method could be looked at), since this helps support the guys that are bringing this stuff to us. I just wish that the paid upgrades would also be downloadable (the shipping kills you --- $8.00 for a $10.00 order).
Cheers,
