Macs are down 16% which is blamed on supply constraints for the new iMac primarily.
Still, the development is rather worrying. But on the other hand, The iPhones (56%) and iPads (20%) need content to be valid products and as long as you can't create iPhone apps on an iPhone or an iPad I think the Macs will live on. And 10% $54.5 billion is still a fair amount of money

It's quite apparent that the Post-PC era is upon us though

I'm just happy has long as I don't have to work in Windows and in FCPX (which is seeing frequent updates, which is encouraging).
