You know how Apple has been gobbling up share in the the university market over the last few years? I have a feeling the Air is going accelerate that growth and become the notebook of choice on college campuses.
It's not just about the money, it's about capability. The $999 MacBook has a 2.4GHz CPU and a 250GB hard drive, and the same GPU.
I work in a medical school neuroscience lab with a bunch of grad students and postdocs. Everyone has a Mac laptop, paid for by the lab. Two postdocs have MacBooks. Everyone else has a MacBook Pro. Except the PI who runs the lab, who has an MBA. The only one in the lab. He values small size and weight more than anyone else. He also travels more than anyone else.
Agreed. Students are also likely to have it as their only machine - and IMHO the MBA is a very enticing supplementary computer, but I'd be loathe to have it as my only.
I thought about this this past week when I had to go to the local uni's CS department for something. I peeked into a half dozen classrooms, lots of laptops, mostly dells, a handful of Toshibas, less than 10 MacBooks...the most I saw in one class was 3.
Likewise when I went to the student union to grab some dinner. Hundreds of students all with laptops open, a handful of Macs. I'd say at rates about at the same as market penetration...~10%.
It may be a geographic thing. Certain regions may make MBPs more appealing, or certain schools may subsidize the purchase more. I've noticed similar rates at other schools in the area.
