But how do today's feather-light notebooks measure up in features and performance?

With all the fuss being made about netbooks, you’d think they were God’s gift to computing convenience. Sure, there’s something to be said for those low-cost, low-power machines, but what if you actually need to get some real work done? There’s nothing convenient about being hobbled by an anemic processor, a relatively low-res screen, a shrunken keyboard, and the various other compromises that contribute to a netbook’s cost savings.

For extreme portability in a machine that packs a punch, you’ll need to set your sights higher, to an ultraportable notebook. Ultraportable notebooks are every bit as light, or lighter than, a netbook, with the added benefit of superior features and a more powerful processor. As a general rule, you’ll find your hardiest ultraportables among the business-class models, which are made for both regular travel and all-around productivity. Of course, convenience of this caliber comes at a premium price—usually four to five times the cost of the average netbook.

Thus, choosing an ultraportable is not a decision to be taken lightly. To help you out, we gathered up four elite representatives of the class and put them through rigorous testing. Obviously, we can’t expect any ultraportable machine to have the muscle required for chores like video editing, batch transcoding, or serious gaming. But we do expect these notebooks to accomplish the gamut of typical day-to-day tasks, including photo editing, slide-show creation, and multitasking. And we expect them to offer all the comfort and features necessary for full-fledged computing on the go.

So let’s see how these featherweights fare.
