No.
But, I didn't upgrade to Lion in the way most will have, I bought a new MacBook Air and sold by old MacBook, which forced me to go from Snow Leopard to Lion.
Lion is inferior to SL IMO. Launchpad is the most counter-intuitive and buggy OS overlay I've seen, effectively adding another layer to the install/uninstall process, which sometimes inexplicably won't work. The App Store drives me insane with it's new-found slowness, and for a couple of weeks I encountered a bug where I could not download or update any apps.... the solution - re-install Lion. Plus a few other issues, bugs etc.
And damnit what a horrible experience that was. Downloading Lion on a 1MB connection with a download limit was not a pleasant experience, in the end I had to leave my Air downloading overnight before the damn startup tone woke me up at 5am in the middle of the install!
So, in hindsight, very happy with my MBA purchase, but I would have been so much happier with Snow Leopard.
