How will Apple redesign the ultraslim, seminal MacBook Air that launched dozens of me-too ultraportable laptops? Only Apple knows. But here are some gratuitous musings anyway.
Dell Latitude Z: a 16-inch laptop that's less than 0.8-inches thick and under five pounds.
(Credit: Dell)In a previous post, I said I wouldn't hazard any guesses on what Apple may do with the MacBook Air. And I won't. That doesn't stop me from looking at the most recent ultrathin laptop competition to see where Apple might be able to improve the design that turns two years old in January.
Enclosure: This will be a tough act to follow. The original design was good enough that Apple didn't change it for gen 2--aka Rev. B--of the Air. And the aluminum enclosure was a trendsetter, which all MacBook Pros (and other PC makers) eventually copied.
But that doesn't mean the Air is perfect. The razor-thin slab of aluminum provides little room for ports and connectors. (Apple's implementation is a flip-out set of USB, Mini DisplayPort, audio ports that retract back into the body.)
A design modification that the Dell Adamo uses (some say retrogressed to) was putting the ports on the back (behind the screen). This allows Dell to offer a fuller array of connectors.
Could Apple come out with a tablet version of the Air?
(Credit: OLPC)Hewlett-Packard, for its part, went another route: it just made its Envy 13 slightly thicker (at 0.8 inches) than the Air, allowing a couple more connectors (a second USB port and an SD card slot). HP also molded the base of the Envy in magnesium, which makes it lighter, according to HP.
Then there's just-announced Dell Adamo XPS. This is even thinner than the MacBook Air and puts the CPU-complex-plus-circuit-board (aka motherboard) behind the screen, not underneath the keyboard--standard design practice for all laptops.
Sony Vaio X is a good example of how small and thin a premium laptop can be: it has an 11.1-inch screen.
(Credit: Sony)Of course, there's the recurring rumor that Apple is looking at different materials to make it even lighter while maintaining its famous sturdiness. This could potentially be a combination of aluminum and something like carbon fiber. (Though, as stated above, HP claims that magnesium is the way to go.)
Other possibilities: make one model bigger (wider), a la the Dell Latitude Z, which offers a 16-inch 1600x900 WLED Display and at its thickest point is only 0.79 inches.
Or make it smaller. The Sony Vaio X is a great example of how light (1.6 pounds) and thin (0.55 inches) a premium laptop (technically it's a Netbook) can be.
Tablet? There is the remote possibility that a version of the Air becomes a tablet. And that would mean potentially a new enclosure and new silicon.
Graphics:. The second feature I'll touch on is graphics. A good graphics chip is tough to squeeze into ultrathin designs and this a major feature that set the Air apart from other slim designs, ... Read More
Is there a downside to squeezing a real graphics processor into a 3-pound, ultra-thin laptop? Not if it's a MacBook Air.
Surprise: higher performance = lower heat
After extensive use of two versions (the January 2008 original and October 2008 refresh) of the MacBook Air, my conclusion is that a decent graphics chip can--over the long haul--not only deliver the expected boost in performance but, surprisingly, contribute to better battery life while, even more surprisingly, bringing down the heat to acceptable levels.
First, let me address the original Air. I have used this version now for about 18 months. Though it has been remarkably reliable, the Intel graphics (housed in the chipset) is its Achilles' heel. And I'm talking about heat problems, not performance shortcomings.
The culprit for me is video-intensive tasks (I don't play games). Any extended video turns up the heat to lap-warming, or much toastier, levels. This can get downright uncomfortable at times. Not only does the bottom of the laptop get hot but the keyboard too.
Nvidia'a graphics-oriented chipset (the GeForce 9400M) and Intel's updated processor used in the new version of the Air brings the heat down to lower levels. Overall, this Air runs cooler and longer with the higher-performance graphics. (The Nvidia 9400M graphics chipset is also used in Netbooks from Lenovo and Samsung.)
I won't repeat the performance benchmarks, which have been amply cited in many reviews on the Web. Suffice to say, Nvidia's 9400M delivers better gaming benchmarks (see second link above) than the Intel graphics in the original Air.
And what about newer versions of Intel's chipset? By comparison, the ultra-thin Dell Adamo, an Air rival, uses a Mobile Intel GM45 Express chipset (the successor to the Intel GMA X3100 graphics used in the original Air) for its graphics. In this review, the Adamo was bested consistently by the Air with Nvidia's chipset.
I also see (which is supported in some reviews) better battery life with the newer MBA. Generally, I can squeeze 1.5 to 2.5 hours (depending on what I'm doing) out of the original MBA. With the newer version, it's 2 to 3 hours.
And now that the Air can be had for $1,499 (versus $1,999 for Dell Adamo), it's a fairly reasonable deal. (Remember: the high end version of the MacBook Air debuted at more than $3,000 back in January of 2008.)
Hewlett-Packard was one of the early trendsetters in the ultrathin laptop market with its Voodoo design. But the product has languished for more than a year. What happened--or what will happen--isn't clear.
The ultrathin laptop market is hot and one of the most visible laptop segments today. And activity in this segment has spiked recently in the wake of a raft of new, inexpensive thin laptops from MSI, Acer, and Lenovo, using low-power Intel chips.
HP's Voodoo Envy was a trendsetting ultrathin laptop but it hasn't been updated in a year.
(Credit: Hewlett-Packard)The Apple MacBook Air and Dell Adamo are two of the most prominent designs. The Air has now been refreshed twice. Dell's svelte Adamo was announced in March, complementing its ultrathin business laptop, the Latitude E4200.
But the razor-thin 0.7-inch-thick Voodoo Envy 133--first announced in June 2008--has stood still. ... Read More
