In addition to Lion being released, Apple released new MacBook Airs, new Mac Minis, and a new Thunderbolt Cinema display.
I've been using Lion since early May, due to the fact that I'm an Apple developer and I've had access to the developer previews since earlier this year. Developer Preview 3 and 4 were stable enough for me to run as my main machine, with the GM Seed (retail version) having been released 2 weeks ago, it was just icing on the cake. My system has been very stable, with perhaps the only app to semi-regularly crash being Chrome, which was the norm for me on Snow Leopard as well.
I highly recommend Lion. Mission Control, Launchpad, Versions, the recovery partition, the new About This Mac panel, I could go on and on. This is a good upgrade. Get it.
