I think the big issue here is commercial use vs. personal use.
For someone who is making money (or not) and selling a service in exchange for payment, the rules are there, clear, and set for everyone to follow. One would assume that if they're a commercial photographer/aerial videographer, whey'll have decent equipment, which will require decent investment, and will not see a problem investing in the necessary licenses.
For a hobbyist, or someone using for personal reasons, these rules don't affect these you. The Lily is no way pitched at the professional market, in the same was as the Parrot, and by large, the DJI Phantoms. As
@Ricardodaforce mentions though, it's very simple to make a Phantom "professional ready".
One a side, and back on topic, I pre-ordered one. I have a Parrot drone as a gift and to be honest I hate the thing. I hate not being able to fly it straight, and it wobbling all over the place - that's probably more me than the drone - but I also hate not being able to do anything else, apart from fly the drone.
I often go out in to the desert by myself shooting events, or mountain biking in the mountains outside of Dubai, or walking, whether in the UK or abroad. For this reason, the Lily is a great idea and concept as I can now continue what I love doing and having some different footage of me (which isn't something I have much of) either out shooting, walking or biking.
As a comment I made to a friend who asked how much it was - probably about 1/2 price again a couple of weeks after it's delivered and I get bored and stick it on eBay.
