I'm on the fence, at the moment. I'm still looking for the stability and reliability I had with Tiger; new features are less important, in my opinion. I've had nothing but problems with Snow Leopard, on numerous machines, so if Lion is more reliable I'll upgrade.But the question remains... how many will stick with Snow Leopard when Lion is released?
In other words, I guess we'll have to wait and see if Lion meets the reliability of Tiger. Here's to hoping; the lion is King of the Jungle, after all.
