MacBook Air a Compelling Option for the True Road Warrior

Pros: Ultra-lightweight, ultra-thin, ultra-cool. Great battery life. Display quality is equal to or greater than that of any Mac (or PC, for that matter) notebook. Standard hard drive model reasonably priced.

Cons: Battery not user-replaceable. Memory not upgradeable. No built-in optical drive. Solid-state drive version ultra-expensive.

I finally managed to get my hands on a MacBook Air (MBA) with the optional solid-state drive (SSD). I have read a lot of reviews of the MBA, but very little specifically about the model with the optional SSD.

The MBA is an impressive feat of engineering, although something of a niche player. If you're part of the market segment toward which the MBA is directed, it is well worth the investment.

Is the SSD worth the (significant) extra cost? The answer to that requires a bit more analysis.

Solidly Built

First, the MBA really does fit inside a manila envelope. And at an even 3 pounds, it won't weigh you down, even when traveling light. When I first took the MBA out of the box, my instinct was to treat it like a fine piece of bone china - very delicately. I was in fear of breaking it.

Don't let its diminutive depth deceive you - this is a solid notebook. Despite its thickness (or lack thereof), you eventually see that it is every bit as durable as a standard MacBook, likely due to its aluminum construction.

The screen and full-size keyboard are impressive. The keyboard felt especially solid. The backlit keys are black with white letters, a noticeable and welcome improvement over the shades of gray theme on the MacBook Pro. I manually turn backlighting on and off on my MacBook Pro often. The backlighting is great in very dark conditions, but it actually hurts in low-light situations by washing out the letters on the keys. That's not an issue with the MBA's black keys.

The MBA screen, 13.3" (diagonal) glossy widescreen TFT display with support for millions of colors, appears to be identical to the MacBook's, with the addition of LED backlighting in the MBA. I'm not a fan of glossy displays, but that's just personal preference. The backlighting enables the MBA's display to instantly return to full brightness when you wake from sleep and undoubtedly contributes to its brighter and clearer appearance as opposed to the MacBook. The MBA screen also seems to have a wider viewing angle.

Like the MacBook, the MBA has no dedicated video RAM, but uses the Intel GMA X3100 graphics processor with 144 MB of RAM shared with main memory. It's clearly not designed for gaming or high-end video editing.

Comparing Models

I was fortunate to be able to spend a great deal of time with the base model as well as the upgraded version. Both models include a specially designed miniature version of the Intel Core2 Duo processor with 4 MB on-chip shared L2 cache running at full processor speed, 800 MHz frontside bus, and 2 GB of 667 MHz DDR2 SDRAM soldered to the board. The base model's processor runs at 1.6 GHz and has an 80 GB 1.8" hard drive; the high-end version has a 1.8 GHz processor and a 64 GB solid state drive. Unfortunately, I was not able to swing having both units at the same time to do a side-by-side analysis, so my observations are just that - observations.

There seems to be little to no noticeable difference in processor speeds. The 200 MHz speed difference is negligible, given the likely and intended uses of the MBA. Calling a 200 MHz speed difference "negligible" seems almost insane, given the fact that I well remember rejoicing when Apple introduced the Colour Classic II and I could finally get a Mac running at a whopping 33 MHz, a whole 17 MHz faster than my 16 MHz Classic II.

Response to Criticism

I have read numerous reviews and opinions of the MBA and can say that most (but not all) of the criticism it has received (which is not much, by the way) is unwarranted and can be answered fairly quickly:

Criticism: It has no internal optical drive, ethernet port, FireWire port, or expansion card slot, and it has only one USB port. Therefore it can't be used as a desktop replacement.

Response: The MBA is clearly not intended to be a desktop replacement. If you added all those items, it would be about the same size as a MacBook, thus defeating the whole purpose the model. If you can't live without any of those features, buy something else.

Criticism: The available hard drives are too small.

Response: Although smaller than what we have come to expect, the sizes should be sufficient for the intended uses. With the weak graphics system, you wouldn't be using iMovie or Photoshop - and their correspondingly large files - anymore than you would on the MacBook. Again, yes, there are some things the MBA just can't do (or can't do very well), but then it's not designed to do any of those things.

Criticism: Memory is not upgradeable.

Response: Not the ideal situation, but at least they gave us 2 GB standard.

Criticism: No user-replaceable battery.

Response: I agree; this is a legitimate issue. Apple made a lot of choices when designing the MBA. This is one of the few areas where I believe they had to make a compromise. Time will tell just how big an issue this is. Although you won't be able to swap out a drained battery for a fresh one on a long flight, the internal battery is not necessarily non-user-replaceable. According to MacInTouch, the MBA is not all that difficult to break into.

Likewise, you might be able to upgrade the hard drive when a larger one in the same form factor becomes available. Currently, the 80 GB model is the largest made in the 5mm thick form factor that fits in the MBA.

Remote Disc

I installed Microsoft Office 2004 using the Remote Disc feature. Remote Disc partially compensates for the MBA's lack of an internal optical drive by allowing it to wirelessly "borrow" the optical drive of another Mac - or even a Windows PC. This feature worked flawlessly, though it is clearly slower than a built-in drive. The necessity of using another computer to install CD- or DVD-based software on the MBA is more evidence that it is not intended as a desktop replacement.

If you must have a MBA but can't live without any of the missing features, most of them are available as external options, including a USB SuperDrive (which only works with the MBA, by the way), a USB ethernet adapter, and a USB modem.

Although I did not test it, the MBA can boot from a remote disc, giving some insurance in the unlikely event a catastrophic crash requires reinstallation of the OS.

Multitouch Trackpad

A less-hyped, but nonetheless compelling, feature of the MBA is its trackpad. The trackpad has the same Multitouch feature a the iPhone. Drag two fingers up or down the trackpad to scroll up and down a web page. Twisting two fingers rotates an image in Preview. Pinch and open gestures zoom images.

I don't own an iPhone, so this was my first introduction to Multitouch. The more I use it, the more I miss it when I go back to my iMac. It's almost addictive.

Migration Assistant Failure

One significant issue I encountered was the inability to use Migration Assistant wirelessly. Despite several attempts, including one where it was left to itself for several hours, Migration Assistant never worked. It continued to (apparently) hang up while "calculating" the size of the files to migrate. The MacInTouch review above reports similar problems.

I did not purchase the USB ethernet adapter so I don't know if that would have solved whatever issue I was having.

Performance Comparison

Although the lack of perceptible speed difference in the 1.6 vs. the 1.8 GHz models was not unexpected, the apparently equivalent performance of the ATA hard drive vs. the SSD was both unexpected and disappointing. An SSD has no moving parts, unlike a standard hard drive in which the drive head has to traverse across a spinning platter to find the information it needs. Theoretically, the SSD should noticeably outperform a hard drive.

If it does, I didn't notice it in the MBA. Granted, both models I evaluated had little additional software installed, meaning their drives were less than half full. One benchmark published on Mac Rumors purports that the SSD will eventually make a great difference when more software is loaded and the drive becomes more fragmented. Obviously I can't vouch for this, but it certainly makes sense.

Flash Drive Worth It?

Is the SSD worth it? It depends. If you're expecting knock-your-socks-off performance gains over the hard drive, then no - at least not at first. If you are a true road warrior, constantly lugging your Mac around the world, and are concerned about durability, then probably yes.

Just to emphasize: the SSD has no moving parts. No head to clang against the platter, obliterating gigabytes of data or killing the hard drive altogether. Although the MBA, like other Mac notebooks, is equipped with technology that is supposed to park the head when it detects the Mac going into free-fall, and thus guard against a hard drive crash, I don't want to place all my data-storage eggs in that basket. With the SSD, even if your MBA is destroyed while dropping off your desk onto the floor, your data should still survive.

Another reason to purchase the SSD model is longer battery life. Apple advertises 5 hours of battery life with the MBA. I was not able to get quite 4 hours with the hard drive model. With the SSD, I actually exceeded the 5 hour mark by almost 4 minutes, including run time on reserve power, before it shut off altogether.

While both models are cooler on the lap than the MacBook or the MacBook Pro, the SSD model seemed to be a tad cooler than the ATA model.

Bottom Line

The MacBook Air is a compelling purchase for the true road warrior. It adds far less heft to your carryon baggage than any notebook on the market. Its battery life is outstanding, though once the battery is dead, that's it until you get to an outlet to recharge.

If you're not necessarily a road warrior, but someone who lives to be on the bleeding edge of technology and to own the latest, greatest, coolest gadget, then you should immediately stop reading this column, go purchase a MBA, and then return to finish reading. Right now there is no electronic device in the world as hip and fashionable as the MBA.

Instantly Sold on It

When my wife first saw an ad for the MBA, she was sold. Its svelte form factor and light weight did it for her. Bulk and weight are the two main reasons she has only carried a notebook around when absolutely, unavoidably necessary, despite the fact that having one with her would often be handy. A secondary reason was the small track pads, which caused her fingers to grow fatigued easily. In addition to portability, she enjoys working on a notebook while sitting on the couch watching TV, but the combination of weight, trackpad, and eventual heat buildup usually make this a short proposition.

The MBA ran the table on her reasons not to carry a notebook, so she is now the proud owner of a MBA that she can't put down. Although she doesn't fit either profile of the classic MBA user, I suspect there are more than a few individuals out there in the same situation.
