Yep, it's just been released today actually.

So far everything I've tried seems to be working perfectly, which normally isn't the case when switching from one OS to the next.
Really quick and painless way to do this.
All the programs, folders and documents stay exactly where you left them, including all the settings, preferences, bookmarks and just about everything you can think of.
The only difference being that the actual OS gets replaced from being OS X Snow Leopard to OS X Lion.
Quite a few new features added. Over 250 are listed on the Apple site.
The first things I've noticed is how iOS and OS X seem to be coming together with this Lion.
Basically taking the best from both worlds and throwing away old things that don't work or replacing them with things that feel a lot more natural.
Only tried out a fraction of what the new OS can do and accidentally discovered some features I wasn't even aware of before.
Can't believe they actually sell this for $30 instead of $300 like others do.
The multitouch implementation alone is something that will change how computers are used in the future as I'm sure it'll get copied in the years to come.
