I believe they are try to capture what they have learned from the iPad (not iPod) and feed that back into the desktop experience. ; I am happy to have options and glad Apple continues to innovate.
Need to check out the new MacBook Air, looks fantastic.
Might be time for me to check out Aperture again, but it would have to be outstanding for me to switch from Lightroom.
I did install Facetime for the desktop which will allow me to connect with my wife's iPhone 4.
