MacBook Air has an iPad operation on a laptop

by Walter S. Mossberg

Some of the nicest, if little discussed, benefits of using an Apple tablet iPad are that it starts instantly, resumes where you left off, and has a long enough battery life that you aren’t constantly fretting about running out of juice or looking for to place to plug it in. And it can do a lot of things for which people use laptops.

What if somebody designed an current laptop that worked this way – you know, a computer with a real keyboard and a larger screen that could run traditional computer software and store more files than an iPad? And what if it was almost as light and portable as an iPad? Well, somebody you have, and that somebody is Apple itself.

The computer in question is the company’s new MacBook Air, which went on sale last week, starting at $999-a price that’s very low for an Apple laptop, though hardly to bargain for a Windows one. The new Air comes in two sizes.The base $999 model has an 11.6-inch screen (vs. 9.7 inches for an iPad) and weighs 2.3 pounds (versus 1.5 pounds for an iPad). The larger-but still thin and light-model starts at $1,299, has a 13.3-inch screen, and weighs 2.9 pounds.

I’ve been testing both versions, but especially the 11.6-inch model, and I find that, despite a few drawbacks, they really do offer the different, more iPad-like experience Apple claims they do.Battery life is strong, and the wake up from sleep is almost instant, even after long periods of being unused.

Their predecessors in the Air Like family, these are gorgeous, very thin and light, but very sturdy aluminum computers. And, like their predecessors, or like iPads and smartphones, they rely on solid-state storage-flash chips instead of conventional hard disk to hold all your files.But Apple has dramatically reduced the physical size of the flash storage to make room for larger sealed-in batteries, so battery life is longer.It has also cut the price from the last version of the Air, a 13-inch model that cost $1,799 with a solid state drive.

Also, the company has re-engineered the way these new Airs sleep, adding a long “standby” period of very low power consumption that Apple says lasts up to 30 days. This standby mode kicks in after about an hour of idle time, and replaces the traditional system, where your current activity is saved to hibernation to conventional hard disk just before the battery dies. With hibernation, getting back to where you were can be slow and somewhat uncertain.With the new “standby” mode, the process just takes a few seconds, only a bit longer than normal sleep.

These are just the first of a number of changes Apple plans in order to make its computers behave more like the iPhone and iPad, without losing their greater power and more traditional keyboards, and mice, and ability to run programs conventional touchpads.

For instance, Apple has said it will soon enter an “app store” for the Mac, which would make it simpler to find and download programs for the computers, and notify users of updates. And it will also roll out, in its next Mac operating system, called Lion-due next summer-a system of apps icon screens, like those on iPhone and iPads, that you can flick through with the company’s multitouch touchpad gestures.

In my harsh battery tests, I found the two new Air models almost matched Apple’s claims, even with all power-saving battery features turned off, Wi-Fi kept on, the maximum brightness and a continuous loop of music playing on screen.The 11-inch model lasted four hours and 43 minutes versus Apple’s claim of up to five hours. The 13-inch model lasted six hours and 13 minutes, versus Apple’s claim of up to seven hours.

This means that, in normal use, with power-saving features turned on, you’d be almost certain to meet, or exceed, possibly Apple’s claimed battery life. For comparison, I did the same battery test on a new Dell 11.6 – inch model, the M101Z, which costs about $450, but is much thicker and heavier than the smaller Air, and uses conventional hard disk.It got only two hours and 41 minutes of battery life, which means that in normal use you’d probably get three to four hours.

The new models are designed to hardly ever require a traditional bootup or reboot.The idea is that you’d only reboot if you had a problem, or installed software that required to reboot, or if the machine had been idle and unplugged more than a month. But even booting is very fast.

In my tests, to cold boot took 17 seconds and a reboot, with several programs running, took 20 seconds. By contrast, the Dell I tested took more than three minutes to fully boot up and be fully ready for use.

Unlike many netbooks, these two new Apples on also have high screen resolutions so you can fit more material into their relatively small sizes.The 13-inch model has the same resolution as Apple’s 15-inch MacBook Pro and the 11-inch Air you have greater resolution than the 13-inch MacBook Pro. Also, unlike on many netbooks, they feature full-size keyboards, though the 11-inch model has reduced-size function keys.

The new Airs aren’t meant to be the most robust machines.They use last-generation Intel processors and have only two gigabytes of memory in their base configurations, and their storage is well below typical hard-disk capacities.

For example, the 11-inch, $999 model has a paltry 64 gigabytes of storage; the 13-inch model starts at a still-weak 128 gigabytes of storage, and even the high-end version of the larger model, which costs $1,599, you’ve just 256 gigabytes of storage.And neither storage nor the memory can be expanded the once you choose your initial specs.

I’d recommend buyers of the 11-inch model spend $200 more to double the storage to 128 gigabytes.And people doing a lot of video editing might want to double the memory on either model to four gigabytes, for an extra $100.

Also, as with the earlier Air models, these two lack to DVD drive and an Ethernet port.Apple sells an external drive for $79 and an Ethernet adapter for $29.If you add in all these extras, prices can quickly climb.

They also lack ports called HDMI ports, becoming common on Windows PCs, for easy connection to televisions, and their keyboards aren’t backlit.The two new models do, however, have two USB ports instead of the single USB port in the older Air.

I was surprised to find that even the base $999 model was powerful enough to easily run seven or eight programs at once, including Microsoft Office, iTunes and the Safari browser with more than 20 Web sites open.It also played high-definition video with no skipping or stuttering.

So, if you’re a light-duty user, you might be able to adopt one of the new Airs as your main laptop.If you’re a heavy-duty user, who needs lots of power and file storage, they’re likely to be secondary machines.

Overall, Apple has done a nice job in making these new MacBook Airs feel more like iPads and iPhones without sacrificing their ability to work like regular computers.But, as always with Apple, you’ll pay more than you will with Windows PCs.
