I'd just like to add my voice to the discussion and state that we here are not guilty of complaining or niggling or nitpicking this issue. We are pointing out the obvious!
When the last OS version works...
...and the current one does not...

...and the most current advertising tells us it does...

...then it's not us who have screwed up!
We bought Apple products which Apple said would work together. In this case they don't.
Some understanding, humility and patience is admirable for all of us to practice, but this Lion grief just keeps on coming, doesn't it?
Now that Apple (which used to call itself "Apple Computer", remember?) has added millions of customers accustomed to IOS, they have chosen to hobble the computer side of their line with this new rushed-to-market operating system.
So, we discuss the problems here and offer solutions amongst ourselves. We submit reports to Apple (we've all done that, right?) to alert them of oversights and errors. We even buy products made by other manufacturers which seem to solve this Apple problem.
I appreciate how patient and understanding correspondents to this group are trying to be, but let's all remember that there was a time when Apple was not a music giant or telecom equipment maker.
The company I've given my custom for the last three decades was known for proudly and meticulously supporting the equipment and software they put their name on.
What I have seen from the company this summer has just made it harder and harder for guys like me to "evangelize" for the Apple computer. Maybe I should just become a little more like a Windows-using buyer of a shiny iPad and just demand that my purchase work like it's supposed to?
Not, it seems, that they will listen.
