Another feature of the MacBook that I like is the latch -- or rather, the lack thereof. Unlike the MacBook Pro, which has a narrow button in the front that I sometimes have to fumble with, the MacBook lid lifts with a simple tug. And it closes with a solid thump, once again leaving you with the sense this is a well-built laptop.

One of the selling points of Apple hardware now that it's using Intel chips is that buyers have the best of both worlds when it comes to software. Macs run Mac OS X, of course, as well as Windows, both XP and Vista (though Vista isn't yet fully supported) meaning you're all set if you need to run the occasional Windows program. I haven't tried Apple's Boot Camp software on the MacBook, but using the Parallels virtualization app, I fired up both Windows XP and Vista with no problems. (The internal cooling fans, however, did come on when Vista was running and CoreDuoTemp showed a temperature spike to 139 degrees. It was the only time I've noticed the fans running and any significant heat increase.) Just don't look for the hardware-demanding "Aero" look in Vista -- the MacBook's shared graphics don't support it.

But why would you want to deal with Windows anyway? You're much more likely to stay on the Mac OS X side of things, especially since Apple's next operating system, Mac OS X 10.5, "Leopard," is due out by next spring. Leopard will be a 64-bit OS. The Core 2 Duo chip is a 64-bit processor; 64-bit OS, meet 64-bit processor. User, enjoy.

In fact, it's that new processor that makes the MacBook such a powerhouse. Apple's testing showed it to be about 25 percent faster in some tests than its predecessor. In day-to-day use, it runs seemingly as fast as my current 17-in. Core Duo MacBook Pro -- and that one has a processor with a slightly faster clock speed: 2.16 GHz. I ran my favorite benchmarking test using Xbench to get an idea of how the new MacBook stacks up and it confirmed what I found in regular use. The MacBook scored higher. The 17-incher, no slouch in the speed department, scored a 90 on Xbench; the MacBook turned in a score of 103. That's just shy of the 108 score a new 15-in. MacBook Pro returned when I tested it a couple of weeks ago -- and it had the 2.33-GHz Core 2 Duo.

In other words, Apple's smallest laptop may be missing a few of the features now standard on MacBook Pros -- the lighted keyboard, discrete video RAM, the aluminum shell, higher-resolution screens and expansion options such as FireWire 800 and the Expresscard/34 slot. But in plain ol' performance, the new MacBook can more than keep up with its siblings.
