What amazes me are all the tosser engineers at Apple who won't acknowledge issues that us developers have posted since Lion's first DP. "Mission Control" has the most filed bugs under UI, followed by lagging [full] multiple display and OpenGL support. A friend of mine worked in ProApps on the new FCPX as a design consultant, they experienced extreme frustration as their input as film editors/professionals went seemingly unheard and the end result was far from what the design team(s) suggested.

It seems Apple has their way and no one else, regardless of the market and logic, is able to convince them otherwise. This may have worked in the past, but if this keeps up...

I hope this update fixes the Bug where some people post that they hope this update fixes a Bug without saying what the Bug is ;)
I do believe it is a form of "ant".

But seriously, I agree that it's ridiculous the amount of problems Lion still has. Fortunately, Mountain Lion fixes quite a few (performance-related, at least). Unfortunately, that isn't free.

It's crazy that people are still experiencing issues with OS X Lion considering it has been out for nearly a year.

You mean Mountain Lion is what Snow Leopard was to Leopard. An actual finished OS not a botched half assed release to get people to double dip?

I was thinking in this direction as well - Leopard was cool to me as it was the OS on my first ever Mac - but then I got Snow Leopard and I really got happy!
There are lots of things that personally work for me in Lion, but it lacks the finish that SL gave Leopard

My God, please just make things more stable. I know my MBP is ancient for peeps around here (late 2006 2,16GHz C2d), but when I bought this machine from Apple in March 2007 & switched from Windows, I thought I was in heaven . Until Lion, I had no idea that system freezes, kernel panics, random black screens, etc. existed in the Mac world. And since my machine is so old (& has the ATI X1600 GPU), I can't wait on ML to "fix" the issues in Lion since it won't be supported. Please Apple...just fix Lion for users like me.

In a way, but Leopard was pretty well baked by the time Snow Leopard came around. Lion is still not as stable as it should be.
