I might be going out on a limb here, but I'm willing to bet nearly all Mac Air users are doing it because of the weight/portability. I meant, really, what else does it have going for it? For sure, the screen is nice, but that would not be the primary reason.
I am coming round to be an Air fan, especially as it sounds from reports than with this rev B. Apple has got the internals right. I doubt it is an awesome FCP machine, but then if you really use Pro Apps, then it is likely you will nearly always be better served buying a Desktop.
Here's I beginning to like the Air:
[1] It's the only really portable Mac with a good screen.
[2] It's the only MacBook without a wedge of glass slapped across the display (aside from the $2799 + $50 “anti glare” MacBook 17", which I wouldn't call portable.
[3] It's the only MacBook with a physical trackpad button
[4] It's arguable the best looking machine Apple makes (more noticeable in person than in the photos).
[5] It's the most portable machine Apple makes. If you are carrying your Notebook around (not using a Desktop replacement) this is more important.
[6] When using a notebook, you type on the keyboard and look at the screen. When not using a notebook it might be in a bag or carry case. On these three areas, the Air delivers with a great keyboard, beautiful screen and thin and light chassis.
[7] Handbrake (for DVDs).
[8] All of Apple's other Notebooks are rev A, so the Air is a little more mature.
What nobody seems to mention in all these posts is the simple fact that when something weighs a mere three pounds and has such a lovely, sensuous shape and feel, you are far more likely to reach for it and use it.
A lot of reviewers who actually bought an MBA in 08 mentioned this after they lived with it for a while (Pogue, Fallows, et al). They found themselves simply using it way more frequently than any previous machine they owned.
I really like the new MB alum. Just lovely. But now I am drifting back to purchasing an MBA as my Mac. Besides fitting the uses I intend for it, I just know I will end up actually using it more than any other possible machine. An X300 is nice, but costs more and only runs you-know-what, which i am pretty fed up with.
I guess my point is also sort of related to Mazurka's posts above. The MBA has a usability factor that is amazing but not easily grasped by folk with a count-the-ports-how-big-is-the-HD mentality.
Sorry for the long post. Have been dwelling on this since mid 08 and it finally had to burst out.
That's an excellent point, well made. The feature-checklist and spec-sheet crowd rarely understand Apple's products and dismiss them as underpowered and overpriced.
They usually miss one simple fact. Computers are made for a person to use and Apple seems to understand what people need better than many.
We all know Apple is far from perfect, but the one thing I think do pretty consistently is to bias their thinking towards simplicity and usability wherever possible. It's not a trait exclusive to Apple, but far too often the opposite happens in tech, where usability is sacrificed for other more “important” things.
The Macbook Air in my opinion is ahead of it's time...sort of like the iMac when they first came out.
I remember Windows enthusiasts wetting themselves back in the day cause the iMac had no Floppy Disc Drive or Serial Port, only that weird USB port.
