"Do the other hundreds of machines and OSs not work anymore?"
Course they do. Does apple care or will they/do support them?
Not for long. I doubt if apple cares [maybe a small amount] about whether they "work anymore" no matter what their so called press releases state.
It would be nice if they did like they have in the past but not the way the industry stands now.
It's a rat race more than ever. Apple needs to move forward or ...
Take a look at how apple is squeezing out the third party vendors for example.
"Are people resentful that Apple continues to make newer machines and OSs?"
Now that's a loaded,broad,open question.
Although ... No I don't believe they're resentful of the newer machines and OSs.
I do believe people are resentful that apple fluffs them off as "unwilling migrates".
"What's your point?"
You really can't be serious for such a question,can you?
But.
I believe the 64bit is a push out the door before it's ready just to get apples teeth back in the game. Take a look at apples past record with OSs,hardware etc.
Sure they all were improved with the next generations. That's not the point.
To actually believe apple sent the 64 bit out the door as too pacify the "unwilling migrates" is being gullible at best.
