I think I read that Macbook Airs are becoming increasingly popular
for business users who travel a lot. If that's true, I don't know
why Apple isn't paying more attention to preserving the Mac's utility
for business (word processing, graphics editing, music editing, etc)
even as it adds features to turn the Mac into a vending machine for
music and videos.
Maybe Apple should sell a more expensive version of OS X that is
optimized for power users rather than emulating an iPad.
